The Immigration and Naturalization Service (INS), as directed by Congress, sets the visa requirements for alien performers who want to work in the United States. The INS allows performers who are not U.S. citizens or permanent residents to audition on any visa, but in order to actually work on a film, television, or electronic media project like a video game, they must then get a very specific visa whether it is SAG signatory or not. Production companies, and sometimes talent agents and managers, apply for these visas on behalf of the performers. Due to the INS criteria and cost of transportation, living expenses, and legal fees, these visas are typically granted only to major-role principal players. You do not have to be a member of Screen Actors Guild to qualify for these visas. However, the criteria for the most common of these particular visas (the O-1) require that the performer has been recognized for his/her accomplishment of outstanding achievement (as closely defined by the INS) in a media similar to the one for which the visa is sought. Visas are issued by project, not by time period. Visas cannot be applied for until an employment offer is extended to the performer. O-1 visas are not available to performers who seem promising, but are not yet fully "proven". For further information about visas, you will need to seek out and make contact with an immigration attorney. We are not able to provide references.
