O-1 visa or status is designed for aliens of extraordinary ability or achievement in the sciences, education, business, athletics, and arts. The "extraordinary ability" of O-1 visa requirement means that the individual is one of the small percentage who has risen to the very top of their field of endeavor.
O-1 petitions may only be filed by a U.S. employer, a U.S. agent, or a foreign employer through a U.S. agent. The O-1 regulations provide that if the beneficiary employee will work concurrently for more than one employer within the same time period, each employer must file a separate petition with the USCIS Service Center that has jurisdiction over the area where the alien will perform services, unless an “established agent” files the petition.
