An EB-1A Expert Opinion Letter is a detailed analysis written by an independent expert who evaluates your achievements against the USCIS criteria for extraordinary ability. Unlike the EB2-NIW's three-prong Dhanasar framework, EB-1A follows a two-step adjudication process: first, demonstrating that you meet at least 3 of the 10 regulatory criteria, and second, passing the final merits determination that your evidence collectively proves sustained national or international acclaim.
USCIS adjudicators are generalists who review cases across every field. An expert opinion letter from a recognized authority in your discipline translates your accomplishments into the specific evidentiary language USCIS requires — explaining not just what you achieved, but why it represents the kind of recognition that places you among the small percentage at the very top of your field.
In 2026, USCIS has increased scrutiny on the final merits determination, meaning even petitioners who meet 4 or more criteria can face challenges if the evidence doesn't convincingly demonstrate sustained acclaim. Our experts craft letters that address both the threshold criteria and the qualitative final merits analysis.
Our expert opinion letters are structured to address the specific evidentiary requirements USCIS applies to EB-1A petitions.
You must demonstrate evidence satisfying at least 3 of the 10 regulatory criteria: awards, memberships, published material about you, judging, original contributions, scholarly articles, exhibitions, leading/critical roles, high salary, or commercial success.
Even after meeting 3+ criteria, USCIS performs a qualitative review asking: does the totality of evidence demonstrate sustained national or international acclaim? Are you among the small percentage at the very top of your field?
You must demonstrate that you intend to continue working in your area of extraordinary ability in the United States and that your entry will prospectively benefit the U.S.
