The Department of Homeland Security (DHS) engages in immigration enforcement actions to prevent unlawful entry into the United States and to apprehend and repatriate aliens 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.
Each Office of Immigration Statistics (OIS) Immigration Enforcement Actions Annual Flow Report contains information obtained from CBP and ICE case records and processed by OIS to describe the number and characteristics of foreign nationals found inadmissible, apprehended, arrested, detained, returned, or removed during a given fiscal year. Below are the annual flow reports on enforcement actions.
