WASHINGTON –U.S. Citizenship and Immigration Services (USCIS) has issued revised instructions for USCIS Form I-131, Application for Travel Document.  The instructions include changes, which will become effective March 5, 2008, that require applicants for re-entry permits and refugee travel documents to provide biometrics (e.g., fingerprints and photographs) at a USCIS Application Support Centers (ASC) for background and security checks and requirements for secure travel and entry documents containing biometric identifiers.
