The O-2 category applies to an accompanying alien who is coming
temporarily to the United States solely to assist in the artistic or athletic
performance of an O-1 nonimmigrant. O-2 classification is not available to
an alien accompanying an O-1 alien in the sciences, business, or education.
An O-2 alien must be petitioned for in conjunction with the services of the O-
1 alien to whom he or she provides support and is not entitled to work
separate and apart from the O-1 alien. To qualify for status, O-2 aliens
must:
(1) Be an integral part of the actual performances or events and possess critical skills and experience with the O-1 alien that are not of a general nature and cannot be performed by others; or
(2) In the case of a motion picture or television production, have skills and experience with the O-1 alien which are not of a general nature and which are critical, either based on a pre-existing and longstanding working relationship with the O-1 alien or, if in connection with a specific production, because significant production (including pre- and post-production) will take place both inside and outside the United States and the continuing participation of the alien is essential to the successful completion of the production.
