Interior enforcement refers to the apprehension, detention, and removal of noncitizens already inside the United States, primarily under the authority of Immigration and Customs Enforcement (ICE) and partner agencies. The unauthorized population is widely estimated in the millions, with long-term residents and mixed-status families a large share.
Recent proposals envision dramatically expanded enforcement — large-scale workplace raids, expanded detention capacity, use of expedited removal further from the border, and greater state and local cooperation. Critics raise legal, humanitarian, fiscal, economic, and operational concerns.
Estimates of the cost and economic effects of large-scale removal vary, with most analyses projecting substantial direct enforcement costs, labor-market disruption in sectors heavily reliant on unauthorized workers, and significant family-separation impacts.
