Passport renewals are required if all of the following regarding your most recent U.S. passport are true:
Is undamaged and can be submitted with your application
Was valid for 10 years
Was issued within the last 15 years
Was issued in your current name or you can legally document your name change with original or certified copy of your marriage certificate or the government-issued document evidencing your legal name change
Renewals are done by mail - no need to come in and no appointment necessary. However, if you are coming in for assistance with your renewal (because you have questions regarding your renewal and/or you need a photo), please schedule an appointment.
