As of September 2015, processing times for U.S. passports are four to six weeks for routine renewals, three weeks for expedited applications and eight business days for expedited renewals processed at a passport agency office. The State Department processes expedited renewals for individuals who are traveling within two weeks or who need a travel visa within four weeks. All expedited renewals incur additional fees.
The State Department accepts renewals submitted by mail if the original passport is undamaged, is less than 15 years old and is sent with the application. Additionally, the applicant must have been 16 years or older when he obtained the original passport, and his name must match the name on the original. The State Department accepts passport renewals with legal name changes by mail if the name change is verified with a certified copy of a marriage certificate or a government-issued document. All applicants who are 15 or under must apply for passport renewal in person.
The State Department accepts passport renewal requests on unexpired passports. Some international travel destinations require that a person's passport is valid for six months from the date of travel.
U. S. citizens residing outside of the country can renew passports at the nearest U. S. consulate or embassy. Citizens residing in Canada may renew a passport through mail but must send payment in U. S. funds via a check or money order that is from a U. S. financial institution.
