Section 287(g) of the Immigration and Nationality Act

The Illegal Immigration Reform and Immigrant Responsibility Act (IIRAIRA), effective September 30, 1996, added Section 287(g), performance of immigration officer functions by state officers and employees, to the Immigration and Nationality Act (INA). This authorizes the secretary of the U.S. Department of Homeland Security (DHS) to enter into agreements with state and local law enforcement agencies, permitting designated officers to perform immigration law enforcement functions, pursuant to a Memorandum of Agreement (MOA), provided that the local law enforcement officers receive appropriate training and function under the supervision of sworn U.S. Immigration and Customs Enforcement (ICE) officers.

State and local patrol officers, detectives, investigators and correctional officers working in conjunction with ICE gain: necessary resources and authority to pursue investigations relating to violent crimes, human smuggling, gang/organized crime activity, sexual-related offenses, narcotics smuggling and money laundering; and support in more remote geographical locations.
