You must fill out application form DS-11 at an acceptance or passport agency. This requires that you submit proof of citizenship, give proper ID, pay the fee and provide two passport photos. Minors must also establish parental or guardian consent.
The fees are currently $75 for a passport for applicants 16 and older; minors under 16 pay $20. Applicants 18 and over also pay an agency fee to the agency where they applied for the passport (usually $25).
It takes 4 to 6 weeks to process a passport application. To expedite the process, an extra fee can be paid and the application will be processed in 2 to 3 weeks.
