I received an RFE (Request for Evidence) regarding the critical role — I collected letters from the CEOs of several companies I worked for. But the request also asked me to further prove that these people really are CEOs. How is this properly proven, what documents are accepted — LinkedIn, corporate filings, anything else? Who has gone through this, please share how you responded step-by-step to the USCIS (U.S. Citizenship and Immigration Services) RFE on this point.
