A chemistry, manufacturing, and controls regulatory affairs researcher met three evidentiary criteria (published material, judging, scholarly articles). However, on final merits the AAO found insufficient evidence of sustained national acclaim or that she ranked among the very top of her field. Limited press coverage and peer review activities did not demonstrate differentiation from peers. Appeal dismissed.

An employer petitioned for an engineer to receive EB-1A extraordinary ability classification. The beneficiary met two of ten criteria (judging and scholarly articles). On appeal, the AAO held the beneficiary failed to meet the required three criteria threshold because contributions lacked demonstrated major significance and sustained acclaim in the field was not established.

Cardiovascular researcher met two criteria but needed three. Original contributions criterion failed: guidelines participation and citations lack specific evidence of major significance; reference letters too conclusory; prestigious journal publication alone insufficient. Record does not demonstrate sustained acclaim or top-tier status required for extraordinary ability.

Education counseling business petitioned for school and career counselor beneficiary's O-1A classification. Petitioner claimed seven criteria; director and AAO found none met. Letters lacked evidence of major field significance. Salary was average, not elevated. Appeal dismissed without final merits determination.
