How can you renew your passport that expired in 1983?

To renew a passport that expired in 1983, you will need to apply for a new passport rather than a renewal, as it has been expired for more than 15 years. Start by completing Form DS-11, which is the application for a U.S. Passport, and gather necessary documentation such as proof of identity and citizenship. You must submit your application in person at a passport acceptance facility or a passport agency, depending on your urgency. Additionally, be prepared to pay the applicable fees.
