The Department of State will no longer add visa pages into U.S. passports, beginning January 1, 2016. U.S. passport holders have had the option to pay for the insertion of additional 24-page visa inserts when their valid passports did not have enough space for entry or exit visa stamps.
This option is being discontinued to enhance the security of the passport and to abide by international passport standards. To help limit impact on frequent travelers, the Department of State began issuing 52-page passports to applicants outside the United States for no additional cost on October 1, 2014.
