Stops federal funding to any State or local government that adopts laws or policies limiting cooperation with federal immigration detainers. To keep receiving federal funds, governments must allow timely responses to Department of Homeland Security (DHS) notices and permit holding an individual for up to 48 hours (not counting weekends and holidays) so DHS can take custody.

If a State becomes ineligible, local governments within that State may apply directly to the federal government for funds they would otherwise receive through the State. The change begins with the first fiscal year after enactment.
