Since 2024, TMCEC has been monitoring S.B. 4, the “Texas Illegal Immigration Law.” The bill, originally scheduled to go into effect on March 5, 2024, is still embroiled in federal litigation. TMCEC will continue to monitor this fluid situation and keep constituents apprised of updates. This page is intended to provide a central landing spot for information related to S.B. 4 as it unfolds.
