Immigration Enforcement Actions

The Department of Homeland Security (DHS) engages in immigration enforcement actions to prevent unlawful entry into the United States and to apprehend and repatriate noncitizens who have violated or failed to comply with U.S. immigration laws. Primary responsibility for the enforcement of immigration law within DHS rests with U.S. Customs and Border Protection (CBP), U.S. Immigration and Customs Enforcement (ICE), and U.S. Citizenship and Immigration Services (USCIS). CBP enforces immigration laws at and between the ports of entry, ICE is responsible for interior enforcement and for detention and removal operations, and USCIS adjudicates applications and petitions for immigration and naturalization benefits.
