EB-1A for Biomedical researchers: Kazarian Criteria & AAO Patterns
How biomedical researchers satisfy the Kazarian two-step analysis: which of the ten regulatory criteria are most accessible for this profession, and what final-merits evidence has cleared AAO scrutiny.
Based on 6,362 real USCIS AAO decisions · Last updated May 2026
Short answer
EB-1A requires biomedical researchers to meet at least 3 of the 10 Kazarian regulatory criteria and then clear a final-merits analysis that the petitioner has sustained national or international acclaim. EB-1A denials commonly find that publications and citations alone do not demonstrate sustained acclaim — the missing pieces are typically funded grants from competitive sources and editorial / study-section service that show the field has bet on the petitioner repeatedly..
Most accessible Kazarian criteria for biomedical researchers
The regulation requires that you meet at least 3 of 10 criteria from 8 CFR § 204.5(h)(3). Below are the criteria most commonly satisfied in EB-1A petitions by biomedical researchers, with profession-specific evidence patterns.
- 1
Original contributions of major significance
Methods, assays, or therapeutic candidates cited by independent labs; patents tied to FDA filings; clinical-trial leadership where the trial advances the standard of care.
- 2
Authorship of scholarly articles
First/last-author publications in Cell, Nature, Science, NEJM, JCI, Blood, or top specialty journals with independent citation evidence.
- 3
Service as a judge of others' work
NIH study-section membership, journal editorial-board roles, grant-review service for foundations.
- 4
Membership in associations requiring outstanding achievement
HHMI investigator, NAS membership, AAAS Fellow, or society-elected positions (ASBMB, ASCB, AACR governance).
Final-merits framing under Kazarian step 2
Biomedical EB-1A final-merits decisions tend to look at funded grants, trainee placement (PhDs and postdocs who went on to faculty positions), and citation depth. A strong publication list with thin grant and trainee evidence often fails final merits.
Why EB-1A petitions by biomedical researchers fail at AAO
EB-1A denials commonly find that publications and citations alone do not demonstrate sustained acclaim — the missing pieces are typically funded grants from competitive sources and editorial / study-section service that show the field has bet on the petitioner repeatedly.
For context: across all professions, 5.9% of NIW appeals are approved at the AAO level. EB-1A appeals follow similar dynamics — most denials are at first-pass USCIS, and AAO data reveals which arguments fail at the highest scrutiny level.
