One can become a U.S. Citizen through a variety of means—birth in the United States, birth abroad to a U.S. citizen parent, or through the naturalization process. For all of these, a specific series of legal requirements must be met. At the U.S. Embassy in Lisbon, Portugal we can provide certification of U.S. citizenship for eligible individuals born abroad to U.S. citizen parents. Our US Embassy in Lisbon, Portugal also processes Certificates of Loss of Nationality for those U.S. citizens who would like to give up their U.S. citizenship or believe that they have expatriated themselves.

Consular Report of Birth Abroad (under age 18)
As a U.S. citizen parent(s), you should report your child’s birth abroad as soon as possible to the nearest U.S. Embassy to establish an official record of the child’s claim to or acquisition of U.S. citizenship at birth. The official record will be the Consular Report of Birth Abroad (CRBA), Form FS-240. This form is evidence of U.S. citizenship, issued to a child born abroad to a U.S. citizen parent or parents who meet the requirements for transmitting citizenship under the Immigration and Nationality Act (INA). CRBA applications must be made before the child’s 18th birthday.
Applying for a Consular Report of Birth Abroad
Starting November 21, 2017, all appointments for Consular Report of Birth Abroad (CRBA) applications at U.S. Embassy Lisbon will be made through a mail-in appointment scheduling system in order to provide better service to our applicants.
The option for a CRBA appointment on the Consular scheduling system has been discontinued. Drop-off requests at the Embassy will not be accepted.
This new system will reduce the wait time and help families prepare for the citizenship appointment at the Embassy. For your convenience, you may also apply for your child’s first passport when you report your child’s birth.

Renunciations & Relinquishments
To renounce U.S. citizenship, you must perform a series of actions voluntarily and with intent to relinquish U.S. citizenship. The basic nature and elements of a renunciation are outlined here at travel.state.gov/.
U.S. citizens cannot effectively renounce their citizenship by mail, through an agent, or while in the United States because of the provisions of section 349(a)(5) of the Immigration and Nationality Act. All renunciations and other recognitions of loss of nationality for U.S. citizens in Portugal are processed at the U.S. Embassy in Lisbon, Portugal.
