EB-1A for Environmental and climate scientists: Kazarian Criteria & AAO Patterns
How environmental and climate 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 environmental and climate 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 in this bucket commonly find the publication record strong but the sustained-acclaim evidence thin.
Most accessible Kazarian criteria for environmental and climate 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 environmental and climate scientists, with profession-specific evidence patterns.
- 1
Original contributions of major significance
Datasets or models cited in IPCC / NCA / USGCRP reports, methods adopted by NOAA / NASA / EPA, or projection systems used by other groups.
- 2
Authorship of scholarly articles
Refereed publications in Nature Climate Change, Science, GRL, JGR, PNAS with independent citations.
- 3
Service as a judge of others' work
IPCC lead-author or contributing-author roles, NCA lead-author roles, NSF / NOAA / DOE proposal reviewer service.
- 4
Membership in associations requiring outstanding achievement
AGU Fellow, AAAS Fellow, or society-elected positions.
Final-merits framing under Kazarian step 2
Environmental science is among the more EB-1A-favorable fields when the petition can demonstrate that the field has incorporated the petitioner's work (cited in assessment reports, adopted as standard datasets, replicated by independent groups). Single-paper / single-dataset profiles tend to fail final merits.
Why EB-1A petitions by environmental and climate scientists fail at AAO
EB-1A denials in this bucket commonly find the publication record strong but the sustained-acclaim evidence thin. IPCC / NCA contributions and competitively-awarded grants are the cleanest counter-evidence.
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.
