This bill aims to enhance border security by establishing a dedicated funding mechanism through new fees on remittance transfers. It mandates that money services businesses impose a 37% fee on each remittance transfer sent to "covered countries," which are identified as the top five countries whose citizens or nationals unlawfully entered the United States in the preceding fiscal year. All collected fees are to be deposited into the general fund of the Treasury. The legislation then establishes two distinct trust funds in the Treasury, each receiving 50% of the remittance fees collected annually from the general fund. The first is the Border Security State Reimbursement Trust Fund , designed to reimburse border states for expenditures related to border security enforcement measures, such as deterring unlawful crossings or gaining operational control of the southwest border. States can apply for these funds by submitting receipts of their relevant expenditures. The second fund, the Border Security Trust Fund , is dedicated to federal border security initiatives. These include the deployment of technology to detect and prevent unlawful crossings along the U.S.-Mexico border, the installation of physical barriers at the southern border, and covering wages and salaries for U.S. Border Patrol agents. Both trust funds are authorized to invest unneeded amounts in interest-bearing U.S. obligations, with proceeds credited back to the funds. To prevent excessive accumulation, any combined balance exceeding $50 billion will be rescinded and dedicated solely to deficit reduction, prohibiting its use as an offset for other spending.
