The U.S. Department of State will no longer add visa pages into U.S. passports beginning January 1, 2016. Previously, U.S. passport holders had the option to pay for the insertion of additional 24-page visa inserts when valid passports lacked adequate space for entry or exit visa stamps. The decision to discontinue this service was made to enhance the security of the passport and to abide by international passport standards.
To mitigate the impact on frequent travelers, the Department of State began issuing 52-page passports to all applicants outside the United States starting October 1, 2014 for no additional cost. Applicants within the United States may choose a 28-page or 52-page book.
