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.
USCIS issued a memo to provide guidance for processing and adjudicating Form I-129, filed on behalf of P-2 nonimmigrants. In particular, this memo amends the policy guidance that the Service Centers must contact Headquarters prior to adjudication of reciprocal exchange agreements which have not been previously approved.
