U.S. Citizen Services


In-person services are by appointment only. The consular agencies are accepting payment by credit card only.


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 and Consulates in Spain, we can provide certification of U.S. citizenship for eligible individuals born abroad to U.S. citizen parents. We also process 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.
