If you are in Northern Ireland you are required to apply for the passport service at the U.S. Consulate General in Belfast. Please do not send your application to the Passport Agency in the United States.
Your completed passport application, photograph and all supporting documents should be sent to the Consulate by Royal Mail “Special Delivery”. Your envelope should be addressed to:
American Citizen Services
U.S. Consulate General Belfast
223 Stranmillis Road
Belfast BT9 5GR
To ensure the safe return of your passports, please enclose a pre-paid self-addressed Royal mail Special Delivery envelope with minimum postage paid up to 500 grams. These prepaid envelopes can be purchased from any UK post office. As the Consulate does not keep track of Special Delivery numbers, you are advised to keep a record of your Special Delivery tracking number so you can track your passport’s return to you.
