O-1 is an evidence-heavy classification for people with a strong record of distinction. O-1A and O-1B apply to different fields and evidence standards.
Who this route suits
High-achieving professionals, researchers, athletes, artists, and other qualifying individuals.
O-1A: Sciences, education, business, athletics
For individuals with extraordinary ability in fields other than arts. Evidence typically includes awards, publications, critical roles, high salary, or other recognized criteria.
O-1B: Arts, film, TV
For individuals with extraordinary achievement in motion picture or TV, or distinction in the arts. The standard differs slightly from O-1A.
Petitioner requirement
An O-1 must be petitioned by a U.S. employer, agent, or foreign employer through a U.S. agent.
Important to know
Focus on evidence quality, not job title alone.
