The United States Immigration and Customs Enforcement (ICE; /aɪs/ ⓘ) is a federal law enforcement agency under the United States Department of Homeland Security. ICE's stated mission is to protect the United States from transnational crime and illegal immigration that threaten national security and public safety.
ICE has two primary and distinct law enforcement components, Homeland Security Investigations (HSI) and Enforcement and Removal Operations (ERO), in addition to three supporting divisions: Management & Program Administration, Office of Principal Legal Advisor (OPLA) and 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.
The acting director is Todd Lyons; the agency has not had a Senate-confirmed director since Sarah Saldaña stepped down on January 20, 2017.
