Passport System Reform and Backlog Prevention Act This bill addresses issues related to the passport issuance process, including by providing the Department of State with emergency hiring authorities. Under this bill, the State Department may hire additional personal services contractors to meet the exigent needs of the Bureau of Consular Affairs from FY2024 through FY2026. The State Department may have up to 100 such positions at any given time, and such positions may not be for longer than two years. Furthermore, the bureau must award or expand contracts to implement certain information technology (IT) programs. Specifically, these contracts shall be to (1) provide a digital dashboard to congressional offices to track individual passport applications; (2) establish a program to provide automated messages and notifications to passport applicants, such as notifications of application errors; (3) establish a mobile application to allow passport applicants to communicate with the State Department and submit documents; (4) expand the online passport renewal system to also accommodate routine first-time adult passport applications; and (5) provide rules-based tools to screen online passport renewal applications with no changed biographical information against commercial databases. The bureau must also solicit the private sector for proposals about commercially available technologies that may improve the passport issuance process. The Government Accountability Office (GAO) must report to Congress a comprehensive review of the passport issuance process, including opportunities to enhance the process. The bureau must periodically report to Congress on its progress in implementing the GAO's recommendations.
