Relating to agreements between counties and United States Immigration and Customs Enforcement to enforce federal immigration law.

HB 1491 requires Texas counties to seek written agreements with U.S. Immigration and Customs Enforcement (ICE) under federal Section 287(g) law, authorizing local officers to enforce federal immigration law. The bill mandates that agreements specify their scope, duration, and limitations, and it imposes penalties for non-compliance - including lawsuits by the attorney general and denial of state grant funds for the following fiscal year. This directly affects all Texas counties, as they would be required to enter such agreements or risk losing state funding. The bill does not alter federal immigration law but creates state-level consequences for counties that fail to pursue these agreements.
