Minors ages 16-17 with their own identification can apply for a passport by themselves. However, it is recommended that at least one parent appear in person with the minor to identify him/her and to show parental awareness.
Examples of Parental Awareness
Having a parent accompany the minor when applying,
Listing a parent as the Emergency Contact on the application,
Using a parent’s check to pay the passport fees, or
A signed statement consenting to issuance of a passport from at least one parent (should be accompanied by a photocopy of that parent’s ID).
