SBSRF, authorized by the One Big Beautiful Bill Act of 2025 (Public Law 119-21), was established to address the urgent need for robust and adaptable border security solutions at the state and local levels. SBSRF is a flexible hybrid program designed to reinforce the nation’s border by empowering states and local governments to meet evolving security challenges.

Program objectives include:

• Construction or deployment of a border wall, border barrier, or buoys along the southern border of the United States.

• Any work necessary to prepare the ground at or near land borders to allow construction and maintenance of a border barrier

• Detection and interdiction of illicit substances and aliens who have unlawfully entered the United States and have committed a crime under Federal, State, or local law.

• Relocation of aliens who are unlawfully present in the United States from population centers to other domestic locations.
