Each year, the Department of Homeland Security (DHS) undertakes immigration enforcement actions involving hundreds of thousands of foreign nationals. These actions include the apprehension or arrest, detention, return, and removal from the United States of foreign nationals who are removable under U.S. immigration law.
The Office of Immigration Statistics (OIS) Annual Report presents information on the enforcement action taken in 2011 and key findings in this report include:
