Immigration Detainers: Legal Issues

An “immigration detainer” is a document by which U.S. Immigration and Customs Enforcement (ICE) advises other law enforcement agencies of its interest in individual aliens whom these agencies are detaining. ICE and its predecessor, the Immigration and Naturalization Service (INS), have used detainers as one means of obtaining custody of aliens for removal proceedings since at least 1950. However, the nationwide implementation of the Secure Communities program between 2008 and 2013 has prompted numerous questions about detainers. This program relies upon information sharing between various levels and agencies of government to identify potentially removable aliens. Detainers may then be issued for these aliens.
