Renunciation of U.S. citizenship is a serious and irrevocable act which deserves your thoughtful consideration. It is imperative that you fully understand the nature of its consequences prior to requesting a Certificate of Loss of Nationality. If you decide that this is the course of action you wish to pursue, there are several steps you need to take including arranging an appointment to come into the Embassy to sign the Statement of Understanding, the Loss of Citizenship Questionnaire and/or the Oath of Renunciation, in the presence of a Consular Officer. Please note that the Statement of Understanding clearly states that the action you are taking is irrevocable.
Remember that renunciation is a personal right and can never be exercised by another person (including parents and/or legal guardians).
