This bill mandates a hiring freeze for United States Immigration and Customs Enforcement (ICE) upon its enactment. It explicitly prohibits the obligation or expenditure of federal funds to appoint any new individuals to positions within the agency. Furthermore, the legislation prevents the detailing or transferring of any existing federal employees to ICE. This comprehensive freeze on personnel additions is designed to limit the agency's staffing capacity. The provisions of this hiring freeze will remain in effect indefinitely until Congress enacts a subsequent law that specifically references and modifies or supersedes this particular subsection.
