I worked on a major IT project for the public sector, and it’s recorded in my employment file. I want to understand — will a letter from the legal entity confirming that I worked there count as evidence for the EB‑1 criteria with USCIS? Can press mentions of the project also be submitted? One more question — the project was related to government systems; can I mention that in the petition without providing architectural details or pointing out any vulnerabilities?
An official letter from the legal entity will do, but what matters is what’s written in it — just “worked for us” isn’t enough; it needs to state your role and what you did specifically. Be sure to attach press mentions; that’s independent evidence the officer reads separately from your own claims about your achievements. For the government part — describe it at the level of publicly available information: the scale and purpose of the system, without architecture details; this is standard practice for government-sector cases and nobody expects technical documentation.
And in my letters my managers/colleagues described what I did for the company and how important it was — I also included a letter from a client I consulted for on behalf of my employer, someone more or less external. That item was accepted. Definitely attach press mentions — the officer reads them separately from your own words; it’s an important layer.
A letter from a client of a government project carries more weight than one from the employer — an independent source.
