A mathematics professor self-petitioner sought EB-1A extraordinary ability classification. The AAO affirmed that he satisfied only two criteria: judging and scholarly articles. His original contributions claim failed because citation counts and expert assertions did not demonstrate major significance in mathematics, and he did not reach the three-criterion threshold.
