Immigration and Customs Enforcement (ICE) is a U.S. federal agency under the Department of Homeland Security. Established in 2003, its primary mission is to enforce immigration laws and investigate customs violations. ICE has two main divisions: Enforcement and Removal Operations (ERO), which focuses on deporting individuals who are in the country illegally, and Homeland Security Investigations (HSI), which tackles criminal activities like human trafficking and drug smuggling. ICE works to ensure national security and uphold the rule of law. The agency collaborates with local, state, and federal partners to identify and apprehend individuals who violate immigration laws or engage in criminal activities.
