O-1: Extraordinary Ability or Achievement
O-1 visa classification
Is available for those to work within their field who have
demonstrated they have extraordinary ability. The O-1 visa
classification includes aliens having sustained national or
international acclaim for extraordinary ability in the sciences,
arts, education, business, and athletics, or aliens having a
demonstrated record of extraordinary achievement in the motion
picture and television industries. This category requires
considerable documentation and is best reserved for the most highly
qualified guest professors, researchers, and artists with a high
level of expertise.
The initial period can be up to three years with one-year extensions
allowed. There is no limit on the time an O-1 can remain in the U.S.
as long as he/she continues the same work. If the employer
terminates the employment early, the employer is responsible for
reasonable costs of returning the alien to his or her last place of
residence before the alien's entry to the U.S.
