As seen on ICE.gov:
ICE priorities include the identification and removal of those that have broken criminal laws, threats to national security, recent border crossers and repeat violators of immigration law. Overall, in FY 2012 ICE’s Office of Enforcement and Removal Operations removed 409,849 individuals. Of these, approximately 55 percent, or 225,390 of the people removed, were convicted of felonies or misdemeanors – almost double the removal of criminals in FY 2008. This includes 1,215 aliens convicted of homicide; 5,557 aliens convicted of sexual offenses; 40,448 aliens convicted for crimes involving drugs; and 36,166 aliens convicted for driving under the influence.
ICE continues to make progress with regard to other categories prioritized for removal. Some 96 percent of all ICE’s removals fell into a priority category – a record high.
