Immigration Enforcement: Actions Needed to Better Track Cases Involving U.S. Citizenship Investigations, Report to Congressional Requesters [open pdf - 3MB]
From the Government Accountability Office (GAO) Highlights: "In recent years, some U.S. citizens have claimed that they were mistakenly detained or removed by ICE [U.S. Immigration and Customs Enforcement] and held by CBP [U.S. Customs and Border Protection] on administrative immigration charges. Such charges are based on civil violations of U.S. immigration law, but these charges are not applicable to U.S. citizens. GAO was asked to review issues related to U.S. citizens detained by ICE or held by CBP on administrative immigration charges. This report examines (1) the extent to which ICE and CBP have developed and implemented policies and procedures for investigating the potential U.S. citizenship of individuals its officers and agents encounter; (2) ICE and CBP data on U.S. citizens detained by ICE or held by CBP on administrative immigration charges; and (3) the extent to which ICE has developed and implemented policies and procedures for investigating the potential U.S. citizenship of individuals its officers identify for detainers. GAO analyzed DHS documents and record-level enforcement data, and interviewed DHS officials at headquarters and in the field."
