Microbiology researcher met three initial evidentiary criteria: judging, scholarly articles, and original contributions. AAO sustained appeal finding petitioner demonstrated sustained national and international acclaim through high citation rates, publications in distinguished journals, international presentations, and peer review work indicative of top-tier expertise.

Self-petitioner, physician specializing in clinical and other medicine, sought EB-1A extraordinary ability classification. Met only two of ten criteria: scholarly articles and judging. Failed to demonstrate sustained national or international acclaim or recognition as top practitioner. Record shows accomplished but not extraordinarily able physician.

Pharmacology researcher sought EB-1A extraordinary ability classification. Petitioner claimed fellowships and professional memberships. AAO found fellowships designed for early-career researchers lack prestige, memberships either post-dated petition or lacked stringent requirements, and evidence insufficient to show top-field distinction.

Postdoctoral researcher in biomedical science seeking EB-1A extraordinary ability. Met judging and scholarly articles criteria but failed original contributions criterion. AAO dismissed appeal, finding insufficient evidence that research impact rises to major significance level required for extraordinary ability classification.
