The main purpose of this legislation is to implement a hiring freeze on the United States Immigration and Customs Enforcement (ICE). This means that no new employees can be hired, and current employees cannot be transferred or detailed to ICE. The objective is to limit the agency's ability to expand its workforce, which may be part of a broader strategy to address concerns about immigration enforcement practices. Key provisions of the legislation include a clear prohibition on using federal funds to appoint new individuals to positions within ICE.
