O-1 Status
O-1 nonimmigrant status is for individuals who can demonstrate extraordinary ability or achievement in the sciences, arts, business, or athletics, or extraordinary achievements in the motion picture or television field. An O-1 petition filing must contain sufficient evidence to demonstrate that the beneficiary is one of a small percentage of individuals who has risen to the very top of the field of endeavor. The USCIS has more information.
Dartmouth will consider O-1 sponsorship where the J-1 or H-1B is not appropriate or not available, and the individual is able to meet the regulatory criteria for O-1 classification. Dartmouth O-1 sponsorship is employer-specific.
