ICE Statistics / US Immigration & Customs Enforcement
"In addition to its criminal investigative responsibilities, U.S. Immigration and Customs Enforcement (ICE) shares responsibility for enforcing the nation's civil immigration laws with U.S. Customs and Border Protection (CBP) and U.S. Citizenship and Immigration Services (USCIS). ICE's role in the immigration enforcement system is focused on two primary missions: (1) the identification and apprehension of criminal aliens and other removable individuals located in the United States; and (2) the detention and removal of those individuals apprehended in the interior of the U.S., as well as those apprehended by CBP officers and agents patrolling our nation's borders. In executing these responsibilities, ICE has prioritized its limited resources on the identification and removal of criminal aliens and those apprehended at the border while attempting to unlawfully enter the United States."

The Yearbook also presents data on immigration enforcement actions, including alien apprehensions, removals, and returns. The Yearbook tables are released as they become available.
