G. IRREVOCABILITY OF RENUNCIATION
Finally, those contemplating a renunciation of U.S. citizenship should understand that the act is irrevocable, except as provided in section 351 of the INA (8 U.S.C. 1483), and cannot be canceled or set aside absent a successful administrative review or judicial appeal. Section 351(b) of the INA provides that an applicant who renounced his or her U.S. citizenship before the age of eighteen (or lost citizenship related to certain foreign military service under the age of 18) can have that citizenship reinstated if he or she makes that desire known to the Department of State within six months after attaining the age of eighteen. See also Title 22, Code of Federal Regulations, section 50.20. See also Section 50.51 of Title 22 of the Code of Federal Regulations regarding the administrative review of previous determinations of loss of U.S. citizenship.
Renunciation is the most unequivocal way by which a person can manifest an intention to relinquish U.S. citizenship. Please consider the effects of renouncing U.S. citizenship, described above, before taking this serious and irrevocable action. If you are outside the United States and have any further questions regarding renunciation, please contact the U.S. Embassy or Consulate nearest to you for more information. If you are inside the United states and have further questions about renunciation, please contact the Department of Homeland Security.
