If you run out of pages before your passport expires, submit Form DS-19, Passport Amendment/Validation Application, along with your passport to the address listed on the back of the form. Under “Other Action Requested,” write in Add extra pages. Your passport will be returned to you with the extra pages inserted. There is no fee for this service unless you require expedited service (see “How To Get Your Passport in a Hurry”). Also, if you plan to travel extensively, when you apply for a passport, you may request at no extra cost a 48-page passport.
