Derivative U.S. Citizenship for Adults
June 9, 2021

Applicants 18 years old and over, born outside the United States, may claim U.S. citizenship through his/her biological parent who at the time of the applicant’s birth was a United States citizen.  Once the citizenship claim is established, the applicant qualifies for a first-time U.S. passport.  Applicants 18 years old and over are not eligible for issuance of a Consular Report of Birth Abroad (CRBA).

To request a citizenship appointment, please follow these instructions: Adult Derivative Citizenship Appointment Instructions

If you cannot attend an appointment within this time frame, please attach a letter indicating your specific days of availability. If you are not yet prepared to confirm your appointment, please DO NOT MAIL your packet.

Citizenship appointments are in high demand and appointments can be rescheduled for emergencies only on a case by case basis. If your situation is not considered an emergency, you will need to proceed with the appointment given to you. The Embassy will only entertain requests for emergency rescheduling THREE (3) BUSINESS days prior to the appointment. Applicants who fail to show up for their scheduled appointments must start the appointment request process from the beginning.

7. The applicant must be present at the interview.

8. Please arrive 30 minutes before your appointment time. Your appointment time is not the same as your interview time. Interview times depend on the number of applicants who appear for their appointments as well as the length of processing time for each case.

9. Please bring photos, originals of all required documents, I.D, and all application fees with you on the day of your appointment! Please refer to the Adult Derivative Citizenship Checklist for details on required items.

10. Please come prepared! If your application is incomplete on the day of your appointment, you may be asked to schedule a new appointment. This will require that you start the appointment request process from the beginning.
