Child vs Adult Passport: What Changes at Age 18?
Turning 18 is an important milestone—and it also changes how you apply for a U.S. passport. Once a child turns 18, they are legally considered an adult under U.S. passport law. This means parental consent is no longer required, and the application process follows adult passport rules.
Answer
When a child turns 18, they must apply for a U.S. passport as an adult. Parental consent is no longer required, and child passport rules no longer apply.
Who Issues Passports After Age 18?
All U.S. passports are issued by the U.S. Department of State, which sets different rules for minors and adults. Once you turn 18, you apply under adult passport regulations.
What Changes When a Child Turns 18?
When you turn 18:
- You can apply for a passport on your own
- Parents do not need to sign or appear
- Your passport will be valid for 10 years instead of 5
- You must follow adult application procedures
These changes apply even if you still live with your parents or are financially dependent.
Is a Child Passport Still Valid After Turning 18?
Yes, a child passport remains valid until its expiration date, even after turning 18. However:
- It cannot be renewed
- It must be replaced with an adult passport when it expires
If your child passport expires after you turn 18, you must apply for a new adult passport.
