"This report uses data from the Federal Justice Statistics Program (FJSP) and other published sources to describe the federal enforcement of criminal provisions of the Immigration and Nationality Act (INA, Title 8 U.S.C. 1101). Dual civil and criminal justice responses are authorized under the INA to address persons being in or attempting to enter the U.S. without authorization and persons committing immigration and other crimes while unlawfully in the U.S. The INA covers criminal immigration offenses that are subject to federal arrest and prosecution, including illegal entry into the U.S., illegal reentry after being removed, failing to leave the U.S. when ordered removed, remaining beyond days on conditional permit, bringing in or harboring aliens, marriage fraud, and employer worksite violations. Law enforcement agencies may refer immigration matters to the U.S. attorneys office where the federal prosecutor may file charges against the defendant in U.S. district court, file the matter before a U.S. magistrate, or decline to prosecute. Immigration offenders who are charged with an offense may be convicted and sentenced to a term in federal prison or community supervision."
