A resolution expressing the sense of the Senate that the law enforcement agents and other personnel of the Department of Justice and the Department of Homeland Security, who have been temporarily engaging in civil immigration enforcement operations, should be returned to their primary missions during periods of active hostility with Iran.

SRES 638 is a non-binding Senate resolution expressing that law enforcement personnel from the Department of Justice (DOJ) and Department of Homeland Security (DHS) temporarily assigned to civil immigration enforcement should return to their primary counterterrorism, cybersecurity, and counterintelligence roles during active conflicts with Iran. It specifically targets agents diverted from critical national security duties - such as FBI personnel working on Iranian oil investigations or DHS cybersecurity staff - to immigration work without strategic justification. The resolution cites concerns that this reassignment reduces capacity to prevent terrorist threats, especially following U.S. military actions against Iran. It urges the administration to prioritize national security missions over immigration enforcement during periods of active hostility with Iran.
