Citizenship Services
Claim or Renounce U.S. Citizenship

Overview

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 [Country], 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.

For routine questions on services for American citizens, please review the information available on our website.  You may contact us if you have further questions.  For the quickest and most complete reply, we encourage you to email us at singaporeacs@state.gov.  If you call, please leave a message and we will get back to you as soon as possible.

Applicants coming to the Consular Section of the U.S. Embassy cannot bring large personal electronic devices to the Embassy. Those items include but are not limited to: laptops, iPads, and other tablet devices, or handheld gaming devices.  Effective immediately, the Embassy Local Guard Force cannot store laptops and large electronic devices for customers. Please make arrangements to leave large devices elsewhere before arriving at the U.S. Embassy to avoid inconveniences.
