EB-1A for Chemists and materials scientists: Kazarian Criteria & AAO Patterns
How chemists and materials scientists 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 chemists and materials scientists 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 cite lab-scale work without record evidence of scale-up, licensing, or regulatory adoption.
Most accessible Kazarian criteria for chemists and materials scientists
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 chemists and materials scientists, with profession-specific evidence patterns.
- 1
Original contributions of major significance
Patents on novel synthetic routes, formulations, or materials with industry licensing or pilot-scale deployment evidence.
- 2
Authorship of scholarly articles
Refereed publications in JACS, Nature Chem, Advanced Materials, Nature Materials, with independent citations.
- 3
Service as a judge of others' work
Editorial-board service, ACS / RSC peer review, DOE / NSF grant-review service.
- 4
Original contributions — alternate framing
Methods adopted as industry standards (USP / NF monographs, ASTM standards) carry significant weight.
Final-merits framing under Kazarian step 2
Final-merits framing for chemists tends to favor petitioners whose work has crossed from lab to industrial / regulatory adoption. Patents-with-licenses and standards-committee work consistently outperform publication-only profiles.
Why EB-1A petitions by chemists and materials scientists fail at AAO
EB-1A denials commonly cite lab-scale work without record evidence of scale-up, licensing, or regulatory adoption. Patent licenses or pilot-plant deployment evidence are the cleanest counter.
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.
