Short-term work visas are available to individuals who possess extraordinary ability in the sciences, arts, education, business, or athletics, or who have a demonstrated record of extraordinary achievement in the motion picture or television industry and have been recognized nationally or internationally for these achievements.
A job offer from a U.S. employer is a basic requirement for the O visa. There is no annual limit on the number of people who can receive O visas.
The O nonimmigrant classification includes the following:
O-1A: individuals with an extraordinary ability in the sciences, education, business, or athletics (not including the arts, motion pictures or television industry)
O-1B: individuals with an extraordinary ability in the arts or extraordinary achievement in motion picture or television industry
O-2: individuals who will accompany an O-1, artist or athlete, to assist in a specific event or performance. For an O-1A, the O-2’s assistance must be an “integral part” of the O-1A’s activity. For an O-1B, the O-2’s assistance must be “essential” to the completion of the O-1B’s production. The O-2 worker has critical skills and experience with the O-1 that cannot be readily performed by a U.S. worker and which are essential to the successful performance of the O-1
O-3: individuals who are the spouse or children of O-1’s and O-2’s
