To renew your passport, you will need to follow the instructions provided by the U.S. Department of State. The requirements for renewing your passport may vary depending on your situation, but here are the general steps and documents you will need:

• Form DS-82: This is the U.S. Passport Renewal Application for Eligible Individuals. You can fill out the form online using the Form Filler tool and then print it.

• Most recent passport: You will need to submit your most recent passport with your application.

• Government-compliant photo: You will need to provide a recent passport photo that meets the governments requirements.

• Payment: You will need to pay the passport renewal fee, which varies depending on the type of passport you have and how quickly you need it.

• Mail envelope: You will need to include a self-addressed, stamped envelope with your application if you are renewing by mail.

If you are not eligible to renew your passport by mail, you will need to apply in person using Form DS-11. In this case, you will also need to provide proof of U.S. citizenship, picture identification, and one color passport photo.

It is important to note that if your passport was issued before your 16th birthday, issued more than 15 years ago, damaged, lost, or stolen, you cannot renew it by mail and must instead apply for a new passport in person using Form DS-11.

Additionally, if you are a minor or first-time applicant or your previous passport was issued more than 15 years ago, you must appear in person and complete a passport application using black ink.

Finally, it is recommended that you renew your passport well ahead of any planned international travel, even if it still has a few months of validity left.
