Relating to the provisions required in an interstate compact on border security.

SB 136 establishes requirements for Texas to join or create an interstate compact focused on border security with Mexico. It mandates that any such compact must include provisions for sharing law enforcement intelligence on border activity, building physical or technological barriers, and jointly using state resources like personnel and equipment. The bill defines "illegal alien" according to federal immigration law (8 U.S.C. § 1101) and requires compacts to prioritize border control through detection and apprehension of individuals crossing illegally. This bill applies only to new compacts entered into after its effective date, leaving existing agreements unaffected.
