Claiming U.S. Citizenship

Due to the impact of COVID-19 and associated national restrictions, the U.S. Embassy in London and the Consulates in Belfast and Edinburgh are offering emergency appointments only for passport and citizenship services that require an in-person appearance.

Please see our website at for more information, including how to request an emergency appointment if you have urgent need of travel.


If you were born outside the United States to one or both U.S. citizen parent(s), you might have a derivative claim to U.S. citizenship.  Please consult the transmission requirements.  If you believe that you qualify, please follow the instructions on this page.

If you are under the age of 18, please refer to the Embassy’s Consular Report of Birth Abroad instructions.

If you are aged 18 or above and have never been documented as a U.S. citizen by your parent(s), you are required to follow the information on these pages and schedule an appointment to apply in person.
