U.S. Citizen Services


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 Luxembourg, we can provide certification of U.S. citizenship for eligible individuals born abroad to U.S. citizen parents. We 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.

Please note:  There is no walk-in service for United States citizens who require a service related to notarials, passports, citizenship or birth registration. These services are by appointment only.

Exceptions to the appointment requirements in cases of bona fide Emergency such as:

  • Family death or illness
  • Emergency medical treatment
  • Provision of support to a family member undergoing such treatment
  • U.S. Court summons

Exceptions are made, on a case-by-case basis, at the discretion of the Consular Officer. To request an Emergency appointment Contact the U.S. Embassy by e-mail: luxembourgconsular@state.gov
