The three EB categories
EB-1: Extraordinary ability (self-petition), outstanding professors/researchers (employer petition), multinational managers (EB-1C, employer petition). No labour certification required.
EB-2: Advanced degree professionals or exceptional ability. Requires PERM labour certification unless applying under National Interest Waiver (NIW) which is a self-petition and waives both the job offer and PERM requirements.
EB-3: Skilled workers (2+ years experience), professionals (bachelor's degree) and other workers. Requires PERM labour certification.
