The main purpose of the Passport Notification Act of 2025 is to ensure that U.S. citizens are informed about the expiration of their passports and the process for renewing them. The goal is to help citizens avoid issues related to expired passports, especially when traveling internationally. Key provisions of this legislation require the Assistant Secretary of State for Consular Affairs to notify U.S. citizens about their passport expiration. This notification must occur no later than 180 days before the passport is set to expire.
