This bill, titled the Securing America's Ports of Entry Act of 2025, primarily focuses on increasing personnel and improving operations at U.S. ports of entry. It mandates the Commissioner for U.S. Customs and Border Protection (CBP) to hire, train, and assign at least 1,000 new CBP officers annually above attrition levels until staffing requirements identified by the Workload Staffing Model are met. The bill also authorizes the hiring of support staff, including technicians, to perform non-law enforcement administrative functions, thereby freeing officers for critical duties. The Workload Staffing Model calculations must consider various factors such as seasonal surges, commercial forecasts, historical volumes, and personnel needs for increasing outbound inspection operations. Should the CBP Commissioner fail to meet the annual hiring target of 1,000 officers, the Comptroller General of the United States is required to conduct a review of CBP hiring practices and submit a report to Congress. Furthermore, the bill mandates a report within 90 days identifying infrastructure improvements, detection equipment (especially for opioids), and safety equipment needed at ports of entry to enhance drug interdiction and officer protection. It also establishes new quarterly reporting requirements for temporary duty assignments of CBP officers, detailing numbers, locations, durations, costs, and impacts on reimbursable service agreements. Finally, the bill amends existing law to require more detailed reporting on CBP agreements, including assessments of their economic and security benefits, and mandates that the annual Workload Staffing Model report include progress on hiring targets and summaries of other required reports.
