Directs transfers of specified unobligated federal balances to fund border security projects: one-third goes to U.S. Customs and Border Protection (CBP) for nonintrusive inspection systems so that all northern and southwest land ports of entry reach 100% scanning by February 6, 2034; two‑thirds goes to the Department of Homeland Security (DHS) to support construction of a southwest border wall system. It also allows CBP to pay recruitment, retention, and relocation bonuses to agents under specified limits, and changes asylum-related handling for aliens who arrive from a contiguous territory by requiring return to that territory (or a safe third country) or detention pending credible-fear/asylum proceedings.
