Northern Border Security Enhancement and Review Act

This bill amends the existing Northern Border Security Review Act to update deadlines and requirements for border security assessments. It requires the Department of Homeland Security Secretary to submit a northern border threat analysis by September 2, 2026, and every two years after, with strategy updates due 90 days after each analysis. The bill also mandates classified briefings to congressional committees 30 days after each threat analysis and directs the development of performance measures for Air and Marine Operations within six months of enactment. These changes directly affect the DHS Secretary, congressional committees, and U.S. Customs and Border Protection's operations along the northern border.
