A professional in secure wireless communication claimed extraordinary ability as self-petitioner. AAO affirmed director's finding that petitioner failed to meet at least three of ten regulatory criteria. Evidence does not demonstrate sustained national or international acclaim or position within small percentage at very top of field. Appeal dismissed.

A postdoctoral optoelectronics researcher sought EB-1A. Met judging and scholarly articles criteria. Claimed original contributions based on 1,131 citations but AAO found cumulative citations and ranking do not establish major significance. Only two of three required criteria met. No sustained national acclaim demonstrated.

Self-represented postdoctoral researcher claimed extraordinary ability as scientist based on awards, memberships, published material, and teaching roles. AAO found awards insufficient, memberships not based on outstanding achievement, articles not primarily about petitioner, and teaching roles not at very top level. Appeal dismissed for failure to meet three criteria.

Wireless communications engineer met three evidentiary criteria but failed final merits determination. Accomplished career and peer support letters insufficient; objective documentation did not show sustained national or international acclaim or top field placement.
