EB-2 NIW for Mathematicians and statisticians: AAO Data, Denial Patterns & Evidence
AAO denial patterns for mathematicians and statisticians, with prong-one framing for both theoretical and applied work.
Based on 6,362 real USCIS AAO decisions · Last updated May 2026
Short answer
Across 134 Mathematician / Statistician AAO decisions in our corpus, 7.5% were approved on appeal, 81.3% were denied, and 11.2% were remanded. The single most common denial reason for mathematicians and statisticians is “Applied vs. theoretical impact.” AAO rates are lower than first-pass USCIS rates because these cases were already denied at least once.
AAO outcomes for mathematicians and statisticians (134 decisions)
Read this carefully: AAO numbers reflect petitions that were already denied at least once and appealed. First-pass USCIS approval rates are substantially higher. Use these figures to understand which arguments USCIS finds insufficient at the highest scrutiny level.
Why mathematicians and statisticians get denied at AAO
Most common AAO denial reason in this bucket:
Applied vs. theoretical impact
AAO denials for mathematicians often turn on prong one: theoretical mathematics, however prestigious, is described in the petition as field-internal. Successful cases either (a) translate theoretical work into a downstream applied area (cryptography, climate modelling, biostatistics), or (b) bring substantial publication + grant evidence that the field has invested in the work.
What strong mathematician or statistician petitions tend to include
These are the evidence types that recur in approved Mathematician / Statistician cases. Not every approved petition has all of them, but petitions missing several typically struggle at AAO.
- 1Refereed publications in top journals (Annals of Math, JAMS, JASA, Annals of Statistics) with citation evidence
- 2NSF / NIH / NSA / DARPA grants at PI or co-PI level
- 3Editorial board and peer-review service for credible journals
- 4Conference plenary or invited-session talks (AMS Joint Meetings, JSM, ICM)
- 5Patents or contributions to cryptographic standards (NIST PQC) for applied math
- 6Independent expert letters from non-collaborator senior researchers
How mathematician or statistician cases fit the Dhanasar three-prong test
The Dhanasar framework asks USCIS to evaluate three things together: substantive merit, your positioning to advance the work, and whether waiving the labor cert makes sense on balance. Here is how the prongs typically frame for mathematicians and statisticians.
Prong 1 — Substantive merit and national importance
For applied work, anchor in cryptography, climate modelling, biostatistics, or finance regulation.
Prong 2 — Well-positioned to advance the proposed endeavor
Grants and editorial service are the cleanest "well-positioned" evidence here.
Prong 3 — On balance, waiver is in the national interest
Argue waiver because grant cycles and standards timelines do not align with labor-cert.
What approved Mathematician / Statistician profiles look like
Refereed publications + competitively-awarded grants + a clear applied or national-priority anchor for prong one.
This is a composite based on patterns across 134 AAO decisions — not any single case. Your specific profile may clear with less, or struggle with more, depending on framing.

Aggregate data tells you what AAO has rejected for mathematicians and statisticians. A $10 ai case review tells you which of those failure modes your profile is closest to — prong by prong, with the five most-similar AAO cases pulled directly from the same 6,362-decision corpus.
