Memorandum on Civil Immigration Enforcement: Priorities for the Apprehension, Detention, and Removal of Aliens [open pdf - 641KB]
"This memorandum outlines the civil immigration enforcement priorities of U.S. Immigration and Customs Enforcement (ICE) as they relate to the apprehension, detention, and removal of aliens. These priorities shall apply across all ICE programs and shall inform enforcement activity, detention decisions, budget requests and execution, and strategic planning.... ICE is charged with enforcing the nation's civil immigration laws. This is a critical mission and one with direct significance for our national security, public safety, and the integrity of our border and immigration controls. ICE, however, only has resources to remove approximately 400,000 aliens per year, less than 4 percent of the estimated illegal alien population in the United States. In light of the large number of administrative violations the agency is charged with addressing and the limited enforcement resources the agency has available, ICE must prioritize the use of its enforcement personnel, detention space, and removal resources to ensure that the removals the agency does conduct promote the agency's highest enforcement priorities, namely national security, public safety, and border security."
