The U.S. O-1 visa for individuals with extraordinary ability is intended for foreign nationals who possess extraordinary ability in the sciences, arts, education, business, or athletics, or who have demonstrated a record of extraordinary achievement in the motion picture or television industry. O visas are generally categorized as follows:
1. O-1A: For individuals with extraordinary ability in the sciences, arts, education, business, or athletics (excluding the arts, motion picture, or television industry);
2. O-1B: For individuals with extraordinary achievement in the arts or the motion picture or television industry;
3. O-2: For individuals who accompany an O-1 artist or athlete to assist in their performance. For O-1A visa holders, the assistance provided by the O-2 applicant must be an integral part of the O-1 holder's activities. For O-1B visa holders, the O-2's assistance must be critical to the completion of the production. The O-2 visa applicant must possess critical skills and experience that are necessary for the O-1 visa holder's work and cannot be performed by a U.S. worker;
4. O-3: For the spouse or children of O-1 and O-2 visa holders.
