EB-1A Expert Opinion Letter
Extraordinary Ability Green Card
The EB-1A green card does not require an employer to sponsor you. But it does require you to prove — through independent expert testimony — that you have risen to the very top of your field. That is a demanding standard, and USCIS is applying it with increasing scrutiny. We prepare the expert documentation your petition needs: field-matched independent experts, criteria-specific letters, draft review included.
- ✓Prepared with a field-matched independent expert
- ✓Documents extraordinary ability criteria
- ✓Peer recognition & contribution assessment

The Highest Bar in Employment-Based Immigration — Cleared with the Right Documentation
An EB-1A expert opinion letter is a formal written statement from an independent expert — typically a credentialed academic or senior industry professional — providing an independent assessment of the petitioner's extraordinary ability, their standing in the field, and the significance of their contributions. It is submitted as part of an EB-1A self-petition filed with USCIS on Form I-140.
The EB-1A standard is the most demanding in employment-based immigration. The petitioner must demonstrate sustained national or international acclaim and meet at least three of ten USCIS evidentiary criteria — or demonstrate receipt of a major internationally recognised award. Critically, even meeting three criteria is not enough on its own: USCIS also applies a holistic final merits review, asking whether the totality of the evidence demonstrates extraordinary ability. Expert opinion letters play a role in both stages — establishing individual criteria and supporting the holistic case.
USCIS has increased scrutiny of EB-1A petitions in 2025 and 2026. Generic and template-based letters — letters that could apply to any petitioner in the field — are increasingly insufficient. An effective EB-1A expert letter is built specifically for the petitioner's achievements, their field, and the specific criteria their petition is addressing. Each expert in our network is vetted and matched to the petitioner's exact discipline. You choose the expert from a shortlist. You review the full draft before finalization. Your approval is required before anything is issued.
Four Areas the Letter Typically Covers
Every letter is built around your specific petition, your field, and the criteria your case needs to establish — always case-specific, never templated.
- Extraordinary Ability Standing — Top of Field Assessment
- Original Contributions of Major Significance
- Published Work, Citations & Field Impact
- Expert Credentials & Independence
Six Situations Where an EB-1A Expert Letter Is Typically Needed
EB-1A petitions typically include between three and five expert opinion letters — among the higher volumes of any employment-based visa category. The exact number depends on which evidentiary criteria the petition is pursuing and the strength of supporting evidence already in the record. Each letter is prepared by a different independent expert and addresses a different criterion or aspect of the case, building a layered evidentiary record.

Self-Petition Evidence Package
The core use case. An EB-1A self-petitioner needs multiple independent expert letters — each from a different credentialed expert addressing a specific USCIS criterion. We prepare individual letters matched to each criterion, available individually or as a bundled order.
-
2
Original Contributions of Major Significance
One of the most commonly contested EB-1A criteria. An expert in the petitioner's field assesses the significance of their original contributions — documenting impact, adoption, and influence in terms that a non-specialist USCIS adjudicator can evaluate.
-
3
Critical Role at a Distinguished Organisation
Another frequently challenged criterion. An expert letter can contextualise the petitioner's role, the distinguished status of the organisation, and the significance of that role — with specific reference to the petitioner's responsibilities and measurable impact.

4
RFE — Extraordinary Ability Questioned
When USCIS issues an RFE questioning specific criteria or the holistic merits determination, targeted expert letters directly addressing the questioned evidence are typically included in the response. Rush preparation available in 48 hours for urgent deadlines.

5
Foreign Achievements — Context for USCIS
Petitioners whose achievements, awards, or recognition originate outside the U.S. often need an expert letter that contextualises their significance for a USCIS adjudicator who may not be familiar with the professional landscape in their home country.
-
6
Holistic Review Support
Under the Kazarian framework, USCIS applies a final merits review after criteria are met. Expert letters that address the petitioner's overall standing — not just individual criteria — can support the holistic case that the petitioner is genuinely among the small percentage at the top of their field.
