United States Immigration and Customs Enforcement
United States federal law enforcement agency
United States Immigration and Customs Enforcement (ICE) is a federal law enforcement agency under the United States Department of Homeland Security. Its stated mission is to conduct criminal investigations, enforce immigration laws, preserve national security, and protect public safety. ICE was created as part of the Homeland Security Act of 2002 following the September 11 attacks. It absorbed the prior functions of the Immigration and Naturalization Service and the United States Customs Service.
ICE has two primary and distinct law enforcement components: Homeland Security Investigations (HSI) and Enforcement and Removal Operations (ERO). It has three supporting divisions: the Management and Program Administration, the Office of the Principal Legal Advisor (OPLA), and the Office of Professional Responsibility (OPR). ICE maintains domestic offices throughout the United States and detachments at major U.S. diplomatic missions overseas. ICE personnel (special agents and officers) do not patrol American borders; rather, that role is performed by U.S. Customs and Border Protection (CBP) and the U.S. Coast Guard. The acting director is David Venturella; the agency has not had a Senate-confirmed director since Sarah Saldaña stepped down on January 20, 2017.
ICE has been involved in multiple controversies and has been the subject of increased protests and criticism during the first and second presidencies of Donald Trump, particularly in 2018 and in 2025, with some activists calling for its abolition.
