This bill would allow Texas to independently implement border security measures along the southern border without waiting for federal action, including constructing physical barriers like walls and fences in areas the state's governor determines lack adequate protection. The legislation authorizes Texas to deploy increased law enforcement, surveillance technology, and other security measures it deems necessary to prevent illegal crossings. The state would be permitted to seek reimbursement from the federal government for the costs of constructing barriers and implementing these operational protections. The bill applies specifically to Texas and responds to concerns about the approximately 6.7 million illegal border crossings since 2021, though it does not specify any dedicated federal funding amount or timeline for reimbursement. The legislation would take effect 60 days after being enacted into law.
