State and Local Immigration Enforcement

Section 287(g) of the Immigration and Nationality Act (INA), codified in 8 U.S.C. §1357(g), permits the delegation of certain immigration enforcement functions to state and local law enforcement agencies. Agreements entered pursuant to INA §287(g) (commonly referred to as §287(g) agreements) enable specially trained state or local officers to perform specific functions relating to the investigation, apprehension, or detention of noncitizens during a predetermined time frame and under federal oversight by the Department of Homeland Security’s (DHS’s) Immigration and Customs Enforcement (ICE).
