The U.S. Department of State will discontinue the practice of adding pages to passports and, instead, require a filled passport to be replaced with a fresh book.  Documentation will have to be submitted by December 18 in order to have the extra pages added before the new policy takes effect. New passport holders on the other hand, will be issued a 52-page passport featuring 20 more pages than the current standard passport.  U.S. passports will continue to be valid for 10 years and returning travellers will not have to register or pay for new visas before they expire, as long as they carry them along in their old passport book when travelling to the destinations that require these visas.  For more on the reasons for this decision by the state department, Click here.Passport and US Visa
