DS-5535 / MANTIS — Administrative Processing
We break down three types of security checks when getting a US visa: DS-5535 (supplemental questionnaire), TAL/MANTIS (Technology Alert List) and Clearance (Security Advisory Opinion). What is checked, who is checked, and how long it takes.
What is Clearance (SAO)
Clearance (clearance) — authorization from Washington to issue a visa to a specific person.
Official documents use different names for the same thing:
- Security Advisory Opinion (SAO) — formal name
- Washington Special Clearance — alternative official name
- Administrative clearance or simply clearance — working terms
When a consular officer sends your case for administrative processing, they request an SAO — an opinion from the Department of State, DHS, FBI, the CIA and other agencies about whether it is safe to issue you a visa.
When all agencies respond “clear” — the Department of State sends the consulate a clearance: “you may issue.” In Russian-speaking communities people say “the clearance arrived” — that is the Washington “okay.”
According to 9 FAM (the Department of State’s internal regulation), administrative processing is defined as “clearance procedures or the submission of a case to the Department” — meaning either undergoing clearances or sending the case to Washington for an opinion.
How 221(g), administrative processing and clearance relate
Typical flow:
- At the interview the officer can’t immediately issue the visa — they place a refusal under INA 221(g).
- Then two options: (1) they request documents, including DS-5535, or (2) they ask nothing and say the case is going to additional processing — that is sending it for SAO/clearance.
- While processing is ongoing, the case is formally recorded as “Refused” under 221(g) in the system.
- Once Washington gives the “go-ahead” (favorable SAO), the officer “overcomes 221(g)” and can print the visa.
Key point
Clearance is a temporary authorization. It has a shelf life (deadline) by which the visa must be issued. If the consulate doesn’t issue the visa in time — the clearance "expires" and must be requested again.
Effect on visa validity: for nonimmigrant visas (B, F, J) the validity period of the clearance directly limits the visa validity. If you are placed under Administrative Processing, the visa issued will be limited to a maximum of 1 year, because clearance is valid for one year. Even if the visa category normally allows 5 or 10 years.
Processing is not a denial: fewer than 2% of all Mantis requests result in a visa refusal. 98 out of 100 people under processing receive a visa. Processing is an additional procedure, not a sentence.
Where the numbers come from: the GAO (Government Accountability Office) is an independent auditing body for Congress. Those who want to dig deeper should read the original GAO-05-198 report (2005, PDF, 39 pages). It describes in detail how interagency checks work, why China and Russia account for 76% of Mantis requests, how the FBI held 1000 cases “on hold” for months, and how after university complaints processing times were reduced from 67 to 15 days.
SAO types and validity periods
SAO (Security Advisory Opinion) — a consulate’s request to Washington for interagency review.
The validity depends on the type of check and visa category: from 3 months to 4 years. The names are internal Department of State codewords (call signs) and by themselves mean nothing.
| SAO type | Validity | Who it applies to |
|---|---|---|
| Visas Eagle (“Eagle” — citizenship-based check) | 12 months | Citizens of Russia, China, Iran, Cuba, Vietnam when applying for immigrant visas (EB-1, EB-2, K visas). Checks ties to government, intelligence services, sanctioned organizations. |
| Visas Mantis (“Mantis” — specialty-based check) | 12 months | STEM specialists whose work relates to technologies on the TAL (Technology Alert List). Checks risk of transfer of dual-use technologies. |
| Visas Donkey (“Donkey” — name-based check) | 3 months | Your name or date of birth matched someone in watchlists. Usually a false positive — a namesake. |
| Visas Condor (“Condor” — country-based check) | 3 months | Citizens from the “List of 26” (mostly Muslim-majority countries). Introduced after 9/11 for additional screening. |
| Visas Merlin (“Merlin” — refugee check) | 15 months | Refugees and asylum seekers. Longest check due to complexity of document verification. |

Why Mantis is used
According to the GAO-05-198 report (p. 5), Visas Mantis checks four things:
- Risk of proliferation of weapons of mass destruction
- Risk of developing destabilizing military capabilities
- Risk of transferring weapons to terrorists
- Preserving US advantage in critical technologies
If you are a physicist, chemist, biologist, programmer in certain areas — you will be checked just in case. That doesn’t mean you are personally suspected. They check everyone in those specialties.
Mantis clearance validity by visa category
According to GAO-05-198 (pp. 15-16), Visas Mantis validity varies by visa category.
Students received the longest validity (up to 4 years), workers and exchange visitors up to 2 years, immigrant visas only 12 months.
| Visa category | Clearance validity |
|---|---|
| F-1 (students) | For the program length, but no more than 4 years |
| H-1B, J-1, L-1 | For the period of activity, but no more than 2 years |
| B-1/B-2 (tourists, business) | Up to 1 year, if purpose of visit hasn’t changed |
| Immigrant (EB-1, EB-2, K) | 12 months |
Source: GAO-05-198 (pp. 15-16)
These are permissive validity periods, not mandatory
The consular officer may request a new Mantis clearance at any time, even before the formal period ends, if deemed necessary (new circumstances, change of specialty, etc.).
Condition: same organization, same activity
Dinsmore Immigration
Plainly: Clearance is valid for 12 months only if you return to the same organization where you worked or studied. If you changed employer or university — a new SAO is required.
Good news: if you already have an active clearance, it can be used for a new visa:
Dinsmore Immigration
Plainly: While the clearance is valid, the consulate can issue a new visa without a new SAO — if your circumstances haven’t materially changed and there are no new "flags" on your record.
When clearance loses validity early:
- Student changes academic program or university
- Worker changes employer or position
- Exchange visitor changes host organization
- New negative information appears in databases (CLASS, sanctions)
System is intentionally opaque
Applicants cannot learn whether their clearance has expired. The consulate does not disclose the issuance date or validity. You only find out about "expiration" when the consulate requests new documents or announces a new check. This is by design: to prevent people from "gaming" the system.
For EB-1A / EB-2 NIW from Russia
Visas Eagle (12 months) is usually applied. If you are in a STEM specialty — Visas Mantis is added. Both are valid for one year. Extended student validity does not apply to immigrant visas.
Multiple SAOs at once
An applicant can be subject to several types of checks simultaneously. For example, MANTIS + CONDOR for a scientist from Pakistan. The visa will be issued only after all checks are complete.
F-1 undergraduates under 30 may be exempt from TAL screening
F-1 Undergraduate Exemption: F-1 students under 30 enrolled in undergraduate programs may be exempt from TAL screening even in sensitive fields.
This exemption does not apply to:
- Graduate programs (Master’s, PhD)
- Postdoc and research positions
- J-1 visas (research scholars)
- H-1B and other work visas
Why DONKEY is the most unpredictable?
DONKEY (Visas Donkey) is a name-based check against lists. If your name matches a person on a watchlist, a manual review is required to distinguish identities.
Common names (especially Arabic, Chinese, Indian) often cause false positives. According to Berkeley International Office, such checks can add 4-6 weeks, and sometimes stretch to months.
TAL: Technology Alert List
TAL (Technology Alert List) is not a list of job titles, but a list of topics that may require extra attention during visa adjudication. The document is used by consulates as a guide to identify cases where additional processing may be needed.
Key difference
TAL identifies subjects and knowledge areas, not job titles. Two people with the same job title can fall into different scenarios depending on how the job is described.
There is no “automatic” rule that a specific profession leads to 221(g). Wording of the activity, consistency of information, and context of travel often decide.
TAL origin history
TAL was first created by the Department of State in November 2000. After the September 11, 2001 attacks, the list was substantially updated in August 2002.
Predecessor to MANTIS: Before 1998 there was a CHINEX (China Exchange) program applied only to PRC nationals. In 1998 CHINEX was expanded and renamed MANTIS, covering all countries.
Growth after 9/11: In 2001 there were only 3 Mantis SAO refusals recorded. After increased screening that number rose to 30 in 2002. At the peak (2003-2004) 1,500-2,000 pending cases were being processed simultaneously.
Legal basis: INA Section 212(a)(3)(A) — provision on inadmissibility of persons who may engage in illegal export of technology.
Updates 2025: AI/ML for autonomous weapon systems, advanced semiconductors, biotechnologies related to biosecurity threats, space and satellite technologies were added.
15 TAL categories
TAL cable lists 15 areas considered sensitive (Critical Fields List):
| Code | Field | Examples |
|---|---|---|
| A | Conventional munitions | Warheads, explosives, detonators |
| B | Nuclear technologies | Reactors, uranium enrichment, plutonium, tritium |
| C | Missile systems | Ballistic missiles, launch vehicles, UAVs |
| D | Missile/UAV subsystems | Engines, guidance systems, stage separation |
| E | Navigation & avionics | Inertial systems, GPS, gyroscopes, accelerometers |
| F | Chemical/biotech/biomedical engineering | Virology, toxicology, genetic engineering |
| G | Remote sensing | Satellite imagery, radars, reconnaissance systems |
| H | Computers/microelectronics | Supercomputers, semiconductors, neural networks |
| I | Materials technology | Composites, ceramics, superconductors, stealth materials |
| J | Information security | Cryptography, encryption, cyber security |
| K | Lasers & directed energy | High-energy lasers, particle beams |
| L | Sensors | Night-vision devices, magnetometers, acoustics |
| M | Maritime technologies | Submarines, underwater robots, Stirling engines |
| N | Robotics | AI, automation, CNC machines, pattern recognition |
| O | Urban infrastructure planning | Critical infrastructure (special case) |
Important: understand
The list is so broad that "almost all engineering specialties fall under TAL" (quote from forums). However, having work in a related area does not automatically cause problems: wording and context of application matter more.
Details on category F: Chemical, biotech and biomedical engineering
This category is particularly broad due to dual-use technologies. Includes:
- Aerobiology, biochemistry, pharmacology, immunology
- Virology, bacteriology, mycology, microbiology
- Toxicology, pathology, genetic engineering
- Fermentation, lyophilization, aerosol technologies
- Organophosphorus chemistry, neurochemistry
If your work in these areas has purely civilian applications (pharmaceuticals, medicine, food industry), prepare a description focusing on the end product.
How to assess your risk
The likelihood of additional questions may be higher if:
- Your work is directly related to dual-use technologies
- The role description contains terms from TAL categories
- You work with technologies that have military application
- Your publications or patents touch sensitive topics
- You plan research in a TAL area
What to do
Prepare a plain-language "civilian" explanation of your work in advance. Check how the role is described in your CV and DS forms. Keep one consistent description across all documents.
Trigger words: what may trigger a check
Consular officers use keywords for initial case assessment. Some terms have a high likelihood of triggering additional questions:
- Direct: explosives, weapon systems, missile guidance, drone warfare
- Dual-use: nuclear, reactor, uranium, enrichment, plutonium
- Modern: autonomous systems, computer vision for defense, neural networks for targeting
- Biotech: bioweapons, toxin, pathogen, gain-of-function
What to do: If your work is NOT military-related, use neutral terms. For example: “image processing for quality control” instead of “computer vision for object detection”.
MANTIS (Visas Mantis)
MANTIS (Visas Mantis) is a type of Security Advisory Opinion (SAO) related to technology transfer concerns. It’s triggered when a consulate believes additional review is needed for sensitive technologies.
For the applicant this usually appears as 221(g) and waiting. Sometimes additional information is requested, including DS-5535 or an email questionnaire, but that does not necessarily mean you were formally “assigned MANTIS.”
What to do
Prepare a short plain-language description of your role and travel purposes. Keep identical wording in DS forms, CV, and letters. Answer only the questions asked, without extra detail.
MANTIS statistics: what the data say
GAO-05-198 indicates that the share of refusals among Mantis cases was under 2% (historical data). This does not guarantee the same outcome in every period, but shows that the check itself does not equal a refusal.
Processing time improvements (historical GAO data): In 2003 average Mantis processing time was 67 days. By 2004 it dropped to 15 days due to improved interagency coordination.
97%+ FBI name checks: According to GAO, over 97% of FBI name checks complete within 120 days.
Main effect of TAL/MANTIS: possible increase in processing time, not a denial.
What are Mantis goals?
9 FAM Exhibit I lists four program goals, including preventing proliferation of WMD and deterring transfer of sensitive technologies.
TAL is used as a pointer to topics where knowledge and experience may matter for national security. GAO describes Mantis SAO as related to “sensitive technology transfer concerns” and applied to scientific and technical cases.
Why they say 'sent to Washington'
Because the SAO request goes for interagency coordination in Washington, and the result is returned to the consulate which makes the final visa decision.
Administrative processing times can depend on circumstances and internal coordination. The Department of State states that administrative processing time varies by case, and there are no fixed deadlines.
How to describe your work
Principles for describing work to avoid unnecessary follow-up:
- Use neutral terms if you have a choice
- Focus on the end-use, not technical minutiae
- Avoid ambiguous wording that could read as dual-use
- Don’t underplay or overstate: describe accurately
| Potentially problematic | Neutral wording |
|---|---|
| developing detection systems | developing monitoring systems for product quality |
| working with cryptography | working on user data protection in commercial software |
| researching autonomous systems | researching automation for warehouse logistics |
Important
The goal is not to hide information but to convey the civilian context accurately. If your work truly involves sensitive technologies, describe it honestly.
Countries with elevated scrutiny
Citizenship affects the likelihood and duration of checks. There are three categories of heightened attention:
Non-Proliferation / Export Control countries — countries with nuclear programs or proliferation concerns: China, India, Israel, Pakistan, Russia. Specialists from these countries working in TAL areas almost always undergo MANTIS.
State Sponsors of Terrorism — countries designated by the US as state sponsors of terrorism: Cuba, Iran, North Korea, Syria. Nationals of these countries undergo EAGLE SAO for any contact with TAL areas. A new SAO is required for each application.
Condor List (~26 countries) — mostly Muslim-majority countries: Afghanistan, Algeria, Bangladesh, Egypt, Indonesia, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Pakistan, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, Turkey, UAE, Yemen, etc. CONDOR checks are usually quick (1-2 weeks) but may run in parallel with MANTIS.
Processing times by consulate
Actual MANTIS processing times depend on the consulate and country:
| Consulate/country | Typical time | Notes |
|---|---|---|
| India (Delhi, Mumbai, Chennai) | 4-8 weeks | Can extend to 3-6 months |
| China (Beijing, Shanghai, Guangzhou) | 60-90 days | Often single-entry visas only |
| Pakistan | 2-6 months | Frequent extended delays |
| Russia | 60-90 days | Often single-entry visas only |
| Middle East | 4-12 weeks | Varies by country |
| Europe, Canada | 2-4 weeks | Usually faster |
| Mexico | 2-4 weeks | Moderate times |
Practical advice
If you work in TAL areas, plan for at least 3-6 months buffer. Especially for China, India, Pakistan, Russia.
The 12-month rule
SAO clearance can sometimes be reused under certain conditions:
When SAO can be reused
Application within 12 months from the original clearance. Return to the same organization. Same duties and functions. No material changes in circumstances.
Exceptions to the 12-month rule
State sponsors of terrorism: A new SAO is required for each submission, regardless of time since the previous clearance.
China and Russia: Typically single-entry visas with a maximum validity of 3 months. Re-entry requires a new visa and often a new SAO.
Expired clearance: If more than 12 months have passed since the original SAO, a new MANTIS check is required.
Short-validity visas after TAL
After TAL processing a visa may be issued with shortened validity (short validity). Typical scenarios:
- China, Russia: Single-entry, validity 3 months
- Iran, North Korea: Single-entry, validity 1-3 months
- Other countries: May get multiple-entry but for 1 year instead of standard 3-5 years
2005 change: The Department of State extended Mantis clearance validity from 1 year to 2 years for many cases, reducing frequency of repeat checks.
Deadline for documents: 1 year
If the consulate requested additional documents (DS-5535, research plan, etc.), you have 1 year to provide them. After that the case may be closed and you’ll need to start over.
Documents to prepare for a TAL case
If your work is in TAL areas, prepare these documents in advance:
- CV/resume with full list of publications
- Research Plan: description of planned work
- Invitation Letter from the US organization
- Letter from a professor/supervisor
- Employment Letter: duties, confirmation of no military/defense applications
- Official transcripts (academic records)
- Dissertation abstract (if applicable)
- One-page plain-language description of the research
Key rules
Be specific: vague descriptions create more questions. Explain civilian application: show the work is not for military purposes. Avoid jargon: officers may not understand technical terms. Keep copies of everything you send.
DS-5535: supplemental questionnaire
Download DS-5535: DS-5535 (English, PDF) — official Department of State form. You can fill it out in advance and bring it to the interview — if the officer asks, you’ll be ready. This saves time and shows preparedness.
Is DS-5535 mandatory?
Yes, if the consulate requests it — completion is mandatory. Refusal to complete the form results in visa denial.
Important
Start gathering data immediately after receiving the request. Check the deadline in the letter (usually 14-30 days). If you need more time — write to the consulate. Keep a copy of the completed form.
Common mistake: postponing completion.
Correct approach: start on day one — collecting 15 years of data takes time.
What does DS-5535 ask for?
The form requires detailed information for 5-15 years:
- Social media (all accounts, including inactive)
- Phone numbers and email addresses
- Travel history (all countries)
- Residential addresses
- Employers with contacts
- Education
- Memberships in organizations
Preparation
Prepare old passports for stamps. Pull email archives and bank statements. Create a chronology of employment and residences. Recall all social media, including inactive accounts.
Do consulates check social media?
Yes, the consulate may check provided accounts. Do not try to hide or delete accounts before submission — that looks suspicious. Archives remain; deletion raises questions.
What DS-5535 requests
The form covers 15 years of history (travel, addresses, employment) and 5 years of contacts (phones, emails, social media):
| Category | Period | What to list |
|---|---|---|
| Travel history | 15 years | Countries, dates, addresses, source of funds, purpose |
| Residential addresses | 15 years | All addresses where you lived |
| Employment | 15 years | Employer, address, title, duties |
| Phone numbers | 5 years | All numbers (mobile, work, home) |
| 5 years | All email addresses | |
| Social media | 5 years | Usernames on all platforms |
| Passports | All time | All passport numbers (current and old) |
| Family | Current | Names and DOBs: siblings, children, spouses |
Sources to recover data
Old passports — stamps and visas. Email archives — tickets, bookings. Bank statements — dates and addresses. Tax returns — employers. LinkedIn — career timeline.
How to fill DS-5535 and the email questionnaire
How to answer the consulate’s email questionnaire?
Answer in the email body, not as an attachment. Copy the question from the consulate’s message, then write your answer beneath it. Use plain text without tables.
Critical
Write your response directly in the email body. Copy each question and answer below it. Avoid parentheses, dashes, apostrophes, and quotation marks. Attach CV only if requested.
Is the email questionnaire the same as DS-5535?
No. DS-5535 is the Department of State’s official form. The email questionnaire is a consulate-specific request in free form. Questions may overlap, but the format differs.
Does DS-5535 affect processing time?
Quality of answers influences processing time. Complete and accurate information can speed up the check. Incomplete data or discrepancies with DS-160 prolong the process.
Before sending
Cross-check everything with DS-160. Fill all fields (N/A if not applicable). Check spelling of names and places. Save a copy of everything you send.
Processing times after submitting DS-5535
Typical: 60 days. Realistic: 2 weeks to 12+ months. Status “Refused” or “221(g)” on CEAC is normal and not a final denial.
| Category | Time | Note |
|---|---|---|
| Fast cases | 2-4 weeks | Minimal security concerns |
| Medium | 6-8 weeks (~60 days) | Typical timeframe |
| Long | 3-6 months | Additional checks |
| Extreme | 12-24 months | TAL areas, complex cases |
By consulate:
| Consulate | Typical time | Note |
|---|---|---|
| Mexico | 2 wk - 2 mo | Faster if travel only to US |
| India (Delhi, Mumbai, Hyderabad) | 60+ days | Often 4-6 months for immigrant visas |
| General range | 2 wk - 8+ mo | Some cases 1-2 years |
Approval rate ~99%
If there are no criminal/security background issues, the vast majority of cases are ultimately approved. Source: State Department
Common situations when filling DS-5535
How to fill Travel History?
What to list:
- Each country separately (even if one multi-country trip in Europe)
- Cities, dates, purpose, source of funds, duration
- Short trips (weekend trips) count too
- Each border crossing = separate entry
What NOT to list:
- Layovers without leaving the airport
- Trips to your country of residence
Source of funds — how to answer:
Simple: “personal savings”, “employer”, “parents”, “scholarship”. NO need to provide card numbers, bank statements, or expenditure breakdowns.
If you don’t remember exact dates:
Write approximate: “July 2015, ~1 week.” Better approximate than leaving blank.
How to fill Social Media section?
List:
- All personal accounts for 5 years (Facebook, Twitter/X, Instagram, LinkedIn, TikTok, Reddit…)
- Deleted accounts — mark as “(deleted 2022)”
- Nicknames — mark “(personal account)”
Do NOT list:
- Company/work accounts
- Group accounts
- Passwords (never!)
If you have no social media:
Write “None” — this is fine and not suspicious. Many O-1 scientists and older applicants have no social media.
Important: Check usernames — a typo can point to someone else’s profile.
Do I need to list deleted social accounts?
Yes, if you remember them — list with status deleted or deactivated. The consulate may find traces of deleted accounts. Honesty is important.
- List all accounts, including deleted ones
- Indicate status: active, deleted, deactivated
- Don’t delete accounts before applying
- If you don’t remember a username — describe the platform and period
What to do with approximate dates over 15 years?
Provide approximate dates marked approximately. Better approximate than leaving blank or inventing.
- Check old passports
- Review bank statements for addresses
- Search email archives for work dates
- Use format “approximately January 2015”
How to list a company that closed?
List the company name, dates of employment, and title. In the contacts field write Company no longer exists and, if possible, provide a contact for a former supervisor.
- Provide full company name
- Give your employment dates and title
- Add “Company no longer exists”
- Find a former supervisor contact on LinkedIn
Do I need to list temporary SIM cards?
Yes, list numbers if you remember them. If you don’t remember a number but recall buying a SIM on a trip — mention that.
- Recall all SIM cards used in the last 5 years

Common mistakes when filling
The main mistake: inconsistencies between DS-160 and DS-5535.
| Mistake | Correct approach |
|---|---|
| Omitting trips/addresses | Even short trips and temporary addresses count |
| Empty fields instead of N/A | Always write “N/A” or “None” |
| Discrepancies with DS-160 | Cross-check employment dates, titles, addresses |
| Too many details | “Tourism” is enough; no need to describe every museum visit |
| Tables/attachments instead of plain text | Follow consulate instructions |
| Forgot to sign/date | Check signature at the end of the form |
| Wrong email for submission | Send to the address specified, with case number in subject |
| Delaying submission | The longer you wait, the longer the processing may be |
| Omitting inactive social accounts | Include all accounts, including deleted ones |
| Converting PDF to Word | Use the original PDF from the consulate |
Rule
Better to estimate than omit. Better to write N/A than leave blank.
Consulate email questionnaire after 221(g)
Sometimes the consulate sends a separate email questionnaire in addition to DS-5535 or instead of it. Questions often overlap, but the response format is set by the specific consulate. A response in the wrong format may not be processed.
How to answer the email questionnaire
Consulates (Yerevan, Warsaw, Tashkent, etc.) often require strict formatting. Typical requirements from real emails:
Mandatory
Reply in the email body (body email), not as an attachment. Do not attach the answer as a file. Do not use tables. Insert your answer immediately under each question. Avoid parentheses, dashes, apostrophes and quotation marks.
CV and letters:
- Attach CV only if explicitly requested
- If asked to “attach CV” — attach as PDF
- Spouse must provide their own CV separately if traveling together
Response format:
Example format
Typical question blocks (based on real consulate emails):
- Name and family members traveling
- Port of entry (US entry port)
- Education (most recent to earliest): institutions, degrees, major, years
- Employment history (most recent to earliest): titles, duties, dates, supervisor contacts
- Area of expertise
- Purpose of trip / description of planned work or research
- Host organization: name, address, contact person, phone, website
- Source of funding
- Travel itinerary
- Military service (if any): country, branch, rank, specialty, dates
- Countries visited (all)
- Publications (all works)
- Description of past and planned research
- References (contacts in your country of birth or residence)
- Export license number (if applicable)
How it works: EB-1A example
Situation: Ivan, a Russian citizen, physicist. Received I-140 approval (immigrant petition) under EB-1A. Attends an interview in Warsaw.
Step 1: Interview. The consul sees: Russian citizen (so Visas Eagle) + physicist working with lasers (so also Visas Mantis). The consul says: “Your case is under administrative processing.” In this case the consul cannot decide locally — they need Washington’s clearance.
Step 2: Request to Washington. The consulate sends an SAO request to the Department of State. The request includes full name, education, employer, research area. CEAC status: “Administrative Processing” or “Refused” (221(g)).
Step 3: Agency checks. The Department distributes the request: FBI (criminal databases, terrorism), CIA (intelligence, espionage), Commerce Department (export control). Each agency works at its own pace. Nobody is obliged to meet a deadline. The Department waits for responses from ALL.
Step 4: Clearance received. All agencies respond “clear.” The Department sends the consulate: “CLEARANCE GRANTED.” Validity: 12 months (Eagle + Mantis).
Step 5: Consulate issues visa. The consulate receives clearance and queues the case for visa issuance. There may still be delays: the consulate’s queue, expired medical exam — you might need a new one, holidays, staff shortages.
Problem: Clearance “expires”
Here’s where the system breaks down:
- Jan 2024: Interview, SAO request sent
- Mar 2024: Clearance received (valid until Mar 2025)
- Aug 2024: Ivan waits, consulate silent
- Dec 2024: Ivan still waiting, consulate “processing”
- Apr 2025: Clearance EXPIRES
- May 2025: New SAO request, queue starts from scratch
- Aug 2025: New clearance (valid until Aug 2026)
- Sep 2026: Expired again, third round begins
Each time a clearance expires
The consulate sends a new request to Washington. The request goes to the back of the queue along with all new submissions. The wait restarts from zero.
Consulates try to act quickly
In practice, after the clearance arrives the consulate usually asks you to submit your passport and attempts to issue the visa promptly to meet validity. If you provided passport and documents in time — a repeat check is usually not required.
Real-world practical example
From a Telegram chat
Analysis: 2.5 years equals 30 months. Clearance is valid 12 months. During that time clearance expired at least twice. “It will burn in a few months” means the current clearance is approaching its end. If issuance isn’t completed, a new cycle begins.
Four scenarios of “expiration”
Scenario 1: SAO validity expired (most common)
What happens: Washington granted clearance, but the consulate didn’t issue the visa before it expired. For immigrant visas (EB-1, EB-2, K) that validity is 12 months.
Why: After clearance the consulate places you in a queue for issuance. The consulate has internal delays: staff shortages, holidays, waiting for your medical exam. Meanwhile the 12 months elapse.
What next: The consul must request a new SAO per internal guidelines. Your request goes to the end of the queue with all new submissions. The wait restarts.

Scenario 2: Other components in the case expired
What happens: Clearance is still valid, but other documents in your case have expired.
What may expire:
- Medical exam — usually valid 6 months. TB test is only valid 3 months. If expired, you must retake and pay again
- I-140 (petition) — for EB-1A and EB-2 NIW usually remains valid after approval, but for work visas (H-1B, L-1) it’s employer-linked
- I-20 or DS-2019 — for F-1 and J-1 students/exchange visitors. If expired, a new document from the university is required
- Financial documents — letters of support, bank statements are typically considered current for 3-6 months
Why it’s a problem: The consul may consider that your circumstances changed and request a new SAO “just in case.” They have the right to do so under 9 FAM 504.2.
Scenario 3: Missed the 1-year 221(g) deadline
What happens: The consul refused under 221(g) and requested additional documents. You have exactly 1 year from the date of refusal to submit them.
Important to understand: This is not the clearance validity — it’s a separate administrative deadline for you. Even if your clearance is still valid, missing this one-year window means the case is closed.
What next: You must submit a new visa application (DS-160 or DS-260), pay the consular fee again ($185 or $325), do a new interview, and undergo administrative processing from scratch.

Scenario 4: New information appears in databases
What happens: Clearance is still valid and all documents are current, but new information about you appears in databases.
What may surface:
- CLASS (Consular Lookout and Support System) — a database that aggregates information from all agencies. A new entry can appear if you end up on some list
- Sanctions lists — OFAC maintains the SDN List (Specially Designated Nationals). For Russian citizens this is especially relevant: many banks, defense enterprises, state corporations, and some universities are subject to sanctions
- Denial in another country — if you were refused a visa elsewhere for security reasons
- Job/specialty change — if you moved to a company or field that is more sensitive under TAL
- Criminal case — even if closed, information may appear in databases
In practice the consul usually doesn’t explain the reason for a new SAO. You simply receive notice that your case is back under review.
Summary table: what expires when
| What expires | Validity | What happens |
|---|---|---|
| Visas Eagle (citizenship SAO) | 12 months | Consulate requests a new SAO, queue restarts |
| Visas Mantis - F-1 (STEM students) | Up to 4 years | Valid for the program duration |
| Visas Mantis - H/J/L (workers & exchange) | Up to 2 years | Valid for the period of activity |
| Visas Mantis - B-1/B-2 (tourists/business) | Up to 1 year | If purpose hasn’t changed |
| Visas Mantis - EB-1, EB-2 (immigrant) | 12 months | Consulate requests a new SAO |
| Visas Donkey (name match) | 3 months | Very short validity, high risk of expiration |
| Visas Condor (“List of 26”) | 3 months | Very short validity, high risk of expiration |
| Medical exam | 6 months | Must retake and pay if expired |
| TB test | 3 months | Fresh test needed |
| 221(g) document deadline | 1 year | Case closed; new application & fee required |
| New database info | Anytime | Consulate may request a new SAO |
Particular danger: Visas Donkey and Condor (3 months)
If your SAO is Donkey (name match) or Condor (citizenship), the clearance validity may be only 3 months. In prolonged checks (6+ months) there is a real risk the clearance will expire while the case is pending.
Don’t confuse two different deadlines
Clearance validity (12 months for Eagle/Mantis) is an internal guideline for consulates. You are not told this date and cannot control it.
221(g) deadline (1 year to provide documents) is your legal deadline. If the consul requested documents you have exactly one year. That’s your responsibility.
The first can silently expire and force a new SAO. The second, if missed, causes you to lose the filing fee and start over.
Why cases hang for years
Reason 1: Expiration loop. Clearances expire every 3-12 months, restarting the cycle.
Reason 2: No priority. A repeat request has no priority over new ones.
Reason 3: Nobody is accountable for timelines. Neither the consulate, nor the Department, nor the FBI is legally bound to a specific response time.
Reason 4: Consulate lacks incentive to hurry. To them you are one case among thousands. No motivation to accelerate.
How rules changed: 2005-2025
What happened before 2005
Imagine a factory conveyor where each part needs a quality check valid for only 1 year.
GAO-05-198, p.12
Plainly: The FBI kept 1000 cases suspended "for a very long time." When new rules were agreed, those cases were finally cleared.
GAO-05-198, p.18
Plainly: 700 requests from the Beijing embassy were simply lost in autumn 2003. No one knew for months there was a problem. People waited for responses that would never come.
February 2005: major easing
On February 11, 2005 the Department of State issued a press release expanding Mantis validity:
US Department of State, February 11, 2005
Plainly: The Department, together with DHS, decided to extend Mantis clearance validity for students, exchange visitors, temporary workers and tourists. Previously all clearances were valid only 1 year.
Practical changes:
| Parameter | Before Feb 2005 | After Feb 2005 |
|---|---|---|
| Clearance for F (students) | 1 year | Up to 4 years (or program length) |
| Clearance for H, J, L | 1 year | Up to 2 years |
| Clearance for B-1/B-2 | 1 year | 1 year (no change) |
| Average processing time | 67 days | 14 days (claimed) |
Reality vs claims
In 2005 the Department claimed Mantis processing fell under 14 days. In practice timelines remained much longer: by 2008 immigration attorneys reported average Mantis times of 6-8 weeks.
Typical picture
Official State Department statements are usually more optimistic than reality. Plan with cushion time.
Tightening 2018-2020 (Trump administration)
In 2018 the administration began reducing visa validity (not clearance) for Chinese students in sensitive fields. In 2020 the President issued Proclamation 10043 — restricting entry of certain PRC students and researchers with alleged ties to the Chinese military. Over 1000 visas were revoked.
Current situation (2025)
In July 2025 the Department reviewed visa reciprocity for many countries: for many nations visas are now issued for only 3 months and single entry. This doesn’t directly affect clearance, but changes the overall picture: even with an active clearance the visa may be short.
What this means for you
2005-era rules with extended clearance validity formally remain. But: the consul can request a new SAO anytime; nationals of state sponsors of terrorism don’t get extended validity; visas may be shorter than clearance (especially for PRC nationals); in 2025 visa validity for many countries was reduced to 3 months. Extended clearance periods (4 years for students, 2 years for workers) are theoretical maxima, not guarantees.
Expedite and inquiries
Wait up to 180 days. After 6 months — congressional inquiry. Frequent weekly emails don’t help and can hurt communication.
Timeline of actions
| Waiting time | Action |
|---|---|
| 0-60 days | Wait, this is normal |
| 60-180 days | One polite status request is reasonable |
| 180+ days (6 mo) | Congressional inquiry |
| 12+ months | Consider mandamus |
How Congressional inquiry works
Congressional inquiry — contacting your US congressperson.
How to submit:
- Contact the congressperson for your district (regardless of party)
- Attach a privacy release + brief summary of the situation
- Expect 30-60 days for a response
What it may achieve:
- Not guaranteed to speed things up
- Confirms your case isn’t forgotten
- Sometimes helps “unstick” a stalled case
What is a Mandamus lawsuit?
Mandamus — a federal court lawsuit after prolonged delay.
How it works:
- Filed after 180+ days of waiting
- ~90% of cases resolved without a hearing
- Forces the government to make a decision
- DOES NOT guarantee approval — only a decision
Important:
- Consult an immigration attorney
- Cost: $3,000-10,000+
- Does not negatively affect the case outcome
Typical results (practitioner data):
- 40%: Immediate decision (usually favorable)
- 35%: Accelerated processing
- 25%: No change
A court can only compel a decision, not dictate content. If the case is substantively complex, mandamus may not secure approval.

Don’t
Write every day hoping to speed things up. Multiple inquiries from different congresspeople. Angry letters — they only harm.
What to do
You cannot directly influence clearance. But you can minimize the risk of a “second round”:
-
Track the 1-year 221(g) deadline. If the consul requested documents, set a reminder 2 months before the one-year mark.
-
For prolonged checks, plan for the risk of a “second cycle”. If processing exceeds 10-12 months, the likelihood of clearance expiring grows sharply.
-
Consider escalation when delays are long. Congressional inquiry is free. Mandamus is effective particularly when clearance is nearing expiration.
-
Don’t delay medical exams. Medicals are valid 6 months; TB tests only 3 months. Do them when you expect clearance soon.
After clearance arrives: act fast
When the consulate notifies you that processing is complete and asks for your passport — that usually means clearance arrived. You have up to 12 months before it expires, but the consulate won’t tell you the exact date. Don’t delay: submit your passport and documents as quickly as possible.
How to tell clearance arrived
The consulate usually emails requesting your passport or schedules a delivery date. CEAC status may change from "Refused" to "Administrative Processing" or "Issued." If the consulate suddenly contacts you after a long silence — that’s a good sign.
Applicants’ observations
Inconsistencies are the main problem
DS-5535 and similar questionnaires most often break down because of inconsistencies with DS-160 or CV. Before sending, ensure positions, dates and places match across forms and resume.
Simplicity matters more than polish
The more "polished" wording and extra details you include, the higher the chance of misreading. Describe your work in simple terms and stick to what is asked.
Don’t rely on memory
People often try to reconstruct years of travel from memory and make mistakes. Gather data from passports, tickets, bank operations and calendars rather than estimating.
Email format is critical
Email questionnaires often fail due to wrong format: tables, attachments, complicated punctuation. Reply in plain text in the email body and insert your answer directly below each question.
Updates 2025
Dec 2025: Extreme vetting for H-1B and H-4. The Department expanded “extreme vetting” to all H-1B and H-4 petitions. Social media must be made public for review. If profiles are private, applicants receive 221(g) until manual checks finish. Check social media privacy settings before the interview.
June 2025: Mandatory social media checks for students. DOS required consulates to review social media for all F, M, J applicants (students and exchange visitors). All accounts should be public during review. Trend toward intensified screening.
2025-2026: Official timelines vs reality. DOS claims 80% of SAOs close within 2 weeks. Practitioners see otherwise: 3-12 months for tech and security cases. Don’t rely on official “60 days.” If your work is in TAL areas, plan at least 3-6 months worst-case.

FAQ
Which matters more: job title or job description?
Job description. Two people titled “Software Engineer” can have different scenarios: one builds e-commerce, another develops signal-processing systems.
Wording in CV, DS forms and letters matters more than job title.
Can I omit mentioning sensitive topics?
No. Trying to hide or downplay your real work can lead to discrepancies across documents and worse outcomes. Aim to accurately describe the civilian context, not to conceal information.
- Describe your work honestly but focus on commercial/civilian application
- Keep one consistent version across all documents
- If the work is truly dual-use, do not try to hide it
If I do regular software development, is it TAL?
Routine software development (web, mobile apps, business systems) generally does not fall under TAL.
Heightened attention is more commonly associated with: cryptography, signal-processing systems, autonomous systems, infrastructure-level cybersecurity.
If I work in AI/ML, is that automatically MANTIS?
No automatic link. AI/ML is broad. Recommender systems for e-commerce differ from computer vision for autonomous systems.
Context of application and how the work is described matter.
Does having a PhD or academic degree affect things?
An academic profile alone isn’t a problem, but complex technical topics and research plans may increase the chance of additional questions.
If you have a dissertation or research, prepare a plain-language description of topic and applications.
If I was asked for DS-5535, does that mean MANTIS?
Not necessarily. DS-5535 and email questionnaires may be requested in various 221(g) scenarios.
Quality and consistency of answers matters more than guessing the check type.
How long does MANTIS usually take?
There is no universal timeframe. Travel.state.gov states administrative processing time depends on case circumstances.
Some cases close within 60 days; others take longer. Historical GAO data show processing has varied.
Can I tell if I specifically have MANTIS?
Usually no. Applicants are rarely told the internal classification of checks.
It’s more practical to respond to requested documents correctly than to try to infer the check type.
What makes things worse
Definitely makes it worse
Contradictions between DS forms, CV and letters. Answers "by memory" instead of checked facts. Attempting to hide a passport, citizenship or employer.
If you have no news:
- Check you have submitted all requested items in the correct format
- Send rare, short, unemotional status requests
- Keep a ready document package in case further clarification is requested
