Since 2003, Immigration and Customs Enforcement (ICE) has been the division of the Department of Homeland Security responsible for enforcing federal laws governing border control, customs, trade, and immigration.
ICE was created by combining the investigative and enforcement arms of the former US Customs Service and Immigration and Naturalization Service. Today, it employs over 20,000 people across more than 400 global offices, with an annual budget of around $8 billion.
