State Department to stop adding page inserts to U.S. passports
Supplemental page inserts -- added by the U.S. State Department into valid U.S. passports that lack adequate space for entry or exit visas stamps -- have made frequently used passports fat, signaling a traveler's breadth of international experience.
As of January 1, 2016, however, the State Department has announced it will no longer be inserting the 24-page supplements into passports.
"The decision to discontinue this service was made to enhance the security of the passport and to abide by international passport standards," according to a U.S. State Department statement.
