This bill aims to significantly enhance United States border security by reprogramming specific federal funds. It proposes to reallocate all remaining unobligated balances from amounts made available under section 10301(1)(A)(ii) of Public Law 117-169, which are funds originally designated for IRS enforcement. The legislation outlines a detailed plan for how these funds will be distributed and utilized to address perceived deficiencies in border management and control. The bill mandates that one-third of these reprogrammed funds be transferred to U.S. Customs and Border Protection (CBP) for the acquisition and deployment of nonintrusive inspection systems , aiming for a 100 percent scanning rate at all northern and southwest border land ports of entry by February 6, 2034. The remaining two-thirds are directed to the Department of Homeland Security for the construction of a border wall system along the southwest international border by the same date. Quarterly reports on implementation and cost estimates for the wall construction are also required. To bolster the U.S. Customs and Border Protection workforce, the bill authorizes the Commissioner of CBP to offer various bonuses, including recruitment bonuses up to $15,000, annual retention bonuses up to 15 percent of basic pay, and relocation bonuses up to 15 percent of annual basic pay. Additionally, the legislation amends the Immigration and Nationality Act to mandate that aliens arriving from contiguous territory shall either be returned to that territory or a safe third country, or be detained for further asylum consideration, including a credible fear determination.
