Postdoctoral research fellow in biomedical engineering claimed extraordinary ability. Met three initial criteria: judging, original contributions, and scholarly articles. AAO held petitioner failed to demonstrate sustained national or international acclaim or placement among the very top in the field, citing lack of citation impact and insufficient evidence of upper-echelon status.

AAO held petitioner did not meet the extra criteria and lacked sustained acclaim for top-of-field status.
