“An examination of millions of previously unavailable government records indicates that repeated official statements about the immigration enforcement efforts of the United States are misleading and may have contributed to a widespread public misunderstanding about the essential nature of this program. The new and well-documented view of the nation’s massive immigration enforcement program has been made possible as a result of a Transactional Records Access Clearinghouse (TRAC) analysis of millions of detailed records obtained from the Immigration Courts (EOIR) under the Freedom of Information Act. These administrative courts, part of the Justice Department, are a key part of the government’s program to deport or remove undocumented aliens as well as noncitizens who have been granted legal status to be in this country. The massive study of the administrative actions in the immigration courts has been supplemented by a separate examination of other records collected by the Executive Office for U.S. Attorneys (EOUSA) that document criminal prosecutions in U.S. federal district courts.”
