Immigration Enforcement: Arrests, Detentions, and Removals, and Issues Related to Selected Populations, Report to the Chairwoman, Subcommittee on Immigration and Citizenship, Committee on the Judiciary, House of Representatives [open pdf - 9MB]
From the GAO [Government Accountability Office] Highlights: "In January 2017, the President issued Executive Order 13768 that instructs the Department of Homeland Security (DHS) to enforce U.S. immigration law against all removable individuals. In February 2017, the Secretary of DHS issued a memorandum (2017 DHS memo) establishing policy and providing guidance related to the Executive Order. Within DHS, ICE [Immigration and Customs Enforcement] is responsible for providing safe confinement for detained aliens, including certain vulnerable populations. [...] This report examines (1) ICE data on arrests, detentions, and removals from calendar years 2015 through 2018; (2) the policies in effect for selected populations and any changes ICE made to align these policies with the 2017 DHS memo; and (3) the extent to which ICE collects data on selected populations and what those data show. GAO analyzed ICE data on arrests, detentions, and removals from calendars years 2015 through 2018; reviewed policies and documents on eight populations GAO selected based on ICE policies and input from organizations that represent various vulnerable populations; and interviewed agency officials."
