Policy Memorandum: Revised Guidance on the Adjudication of Cases Involving Terrorism-Related Inadmissibility Grounds (TRIG) and Further Amendment to the Hold Policy for Such Cases [open pdf - 116KB]
"This Policy Memorandum (PM) provides updated instruction to all U.S. Citizenship and Immigration Services (USCIS) offices in adjudicating cases in which an applicant is inadmissible under one or more of the terrorism-related inadmissibility grounds (TRIG) set forth in Section 212(a)(3)(B) of the Immigration and Nationality Act (INA). This PM modifies existing hold guidance for cases involving TRIG to allow for the denial of some cases currently on hold in which a TRIG exemption would not be granted to the individual applicant even if an exemption were available."
