Renunciation of U.S. Citizenship
February 5, 2024

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. A renunciation of U.S. citizenship can never be exercised by another person, including parents and/or legal guardians. Applicants will need to communicate personally with U.S. Consular Section Vienna regarding their renunciation in order to demonstrate from the beginning that they are not subject to duress or undue influence from another party.

Before beginning this process you need to carefully review the legal requirements as well as the consequences and ramifications of renouncing U.S. citizenship: Renunciation of U.S. Nationality Abroad

For questions related to possible tax implications, please contact the Internal Revenue Service and review the Joint Foreign Account Tax Compliance Act (FATCA) FAQ: Internal Revenue Service and Joint Foreign Account Tax Compliance Act

For questions related to Social Security or other federal benefits, please contact the Federal Benefits Unit in Frankfurt: Social Security

If you decide that this is the course of action you wish to pursue, there are several steps you must take as described below, including two separate, in-person interviews at U.S. Consular Section Vienna. You must demonstrate to the consular officer that you fully understand the nature and consequences of the oath of renunciation, that you are not subject to duress or undue influence, and that you are voluntarily and intentionally seeking to renounce your U.S. citizenship.



Please read the information available online at the Department of State and Internal Revenue Service links below regarding the legal requirements for taking the oath of renunciation before beginning the process to request a CLN. Loss of U.S. nationality is irrevocable, and you should fully understand the consequences and ramifications  before beginning this process. 



  • Schedule an appointment for “Notarial and other services.” No fee is collected at this first interview. 
  • On the day of your appointment, please bring the following documents: 
    • ORIGINAL most recent U.S. passport, 
    • ORIGINAL most recent U.S. passport card (if applicable), 
    • ORIGINAL U.S. birth certificate (issued by your State of birth) or
      ORIGINAL Consular Report of Birth Abroad or Certificate of U.S. Citizenship or Certificate of U.S. Naturalization 
    • ORIGINAL most recent Austrian or other second nationality passport or Government-issued ID Card(s) – If you possess multiple nationalities, bring Passport or Government-issued ID for all nationalities 
    • If you do not have a valid Austrian passport, please bring original evidence of your other (non-U.S.) citizenship, or grant of Austrian citizenship (Zusicherungsbescheid) 
    • ORIGINAL proof of any name changes, if applicable (such as marriage certificates or official, court order, divorce decree, etc.), if applicable. 
    • The address of your last residence in the United States.   
  • A consular employee will review your documents for completeness and will provide a checklist if any documents are missing. Your case cannot proceed until all required original documentation is provided.
  • If your case is deemed complete and you confirm your intent to proceed, the date for the second and final interview will be scheduled. The date for the second interview cannot be reserved before completing step 2 of this process.  



  • Documents: On the day of your appointment, you must bring all the ORIGINAL documents you previously presented.   
    • Your U.S. birth certificate (if applicable) will be returned to you on the day of your application. However, your U.S. passport (if applicable) and other proof of U.S. Citizenship (Consular Report of Birth Abroad or Certificate of Naturalization/Citizenship, as applicable) will be retained by the U.S. Embassy in Vienna while awaiting approval.
    • Upon approval of your application, the original Certificate of Naturalization/Citizenship (if applicable) will not be returned to you, but will be forwarded to the Department of Homeland Security  upon the issuance of the Certificate of Loss of Nationality. Your U.S. passport (if applicable) will be canceled, annotated, and returned to you. The Consular Report of Birth Abroad (if applicable) will be annotated and returned to you.
    • If you need to travel to the United States on your U.S. passport after the second interview but before the Certificate of Loss of Nationality has been approved, please inform the U.S. consulate during your second interview.
  • Interview: A Consular Officer will interview you. You will be given another opportunity to review the documents prior to signing them and taking the oath of renunciation.
  • Fee: Immediately prior to taking the Oath of Renunciation, you must pay the non-refundable fee (please click here to see the fee) for processing the request for Certificate of Loss of Nationality. We accept credit cards (preferred), or cash (Euros or Dollars). We do NOT accept personal checks or bank debit, ATM or Bankomat cards. This fee is not waivable, nor is it refundable on the sole basis of denial of your request for a CLN. 

After the interview: U.S. Consular Section Vienna will submit your request to the Department of State for final decision. If your request is approved, the Certificate of Loss of Nationality will be mailed to your home address and the effective date of expatriation is the date you performed the potentially expatriating act as defined in INA 349(a)(1)-(5). The Certificate of Loss of Nationality is the sole legal document establishing loss of U.S. nationality. This approval process can currently take up to 6 months.

NOTE:  The steps above outline the process for requesting a CLN based on taking an oath of renunciation before a U.S. diplomatic or consular officer abroad under Immigration and Nationality Act (INA) Section 349(a)(5), 8 USC 1481(a)(5).  For information on the parallel process to request a Certificate of Loss of Nationality (CLN) on the basis of the commission of another potentially expatriating act under INA 349(a)(1)-(4), 8 USC 1481(a)(1)-(4), please contact ConsulateVienna@state.gov.
