S Visa

CRS Report On Immigration: S Visas For Criminal And Terrorist Informants

The provision establishing the S visa in the INA was originally due to expire on September 13, 1999, but Congress had extended it until September 13, 2001. Aliens admitted through the S visa categories are designated as S-5 and S-6 nonimmigrants. Request for these visas must be filed by a state or federal law enforcement agency, and the filing agency must assume responsibility for the alien from their time of entry until their departure, or until they adjust status.
