Renunciation is one of seven expatriating acts, and the only one most people will ever consider. Section 1481(a) lists them: naturalizing in a foreign state on your own application after turning eighteen; taking an oath or formal declaration of allegiance to a foreign state after turning eighteen; serving in a foreign country's armed forces where those forces are engaged in hostilities against the United States, or serving in them as a commissioned or non-commissioned officer; accepting certain foreign government offices; the formal renunciation before a consular officer abroad in paragraph (5); a formal written renunciation inside the United States before an officer designated by the Attorney General, which is available only while the United States is at war and only with the Attorney General's approval; and conviction for treason or certain related offenses. Every one of them requires the same two conditions in the opening sentence, voluntariness and intent to relinquish. That is why naturalizing in another country without meaning to give up US nationality does not cost anyone their citizenship; and voting in a foreign election is not on the list at all.
The procedure, as the State Department describes it. It begins with the person contacting a US embassy or consulate to request the service. The post provides information on the process and its consequences, and then the person completes two separate interviews with a consular or diplomatic officer. If they still wish to proceed after the first interview, they take the oath of renunciation in person before an officer at the second. The package, including a memorandum recommending approval or denial, then goes to the Department's Office of American Citizen Services for review, which decides whether the burden of proof has been met and whether the renunciation was voluntary and intentional. The regulation at 22 CFR 50.50 adds a specific content requirement: the renunciant must include on the form a statement that they "absolutely and entirely" renounce US nationality "together with all rights and privileges and all duties of allegiance and fidelity thereunto pertaining."
In-person appearance is required, and the Department has considered and declined to change that. Commenters on the 2026 fee rule asked the Department to allow renunciation by videoconference to save the cost of traveling to an embassy. It declined, citing security and fraud concerns and, specifically for this service, the need for the officer to assess in person whether the individual is acting voluntarily and understands the gravity of what they are doing.
The fee is $450, and this changed recently enough that most sources are wrong. Item 8 of the Schedule of Fees for Consular Services, at 22 CFR 22.1, now reads "Administrative Processing of Request for Certificate of Loss of Nationality $450". The history is worth knowing, because it explains why the number in circulation is different. The Department set the fee at $450 in 2010, deliberately below cost, "in order to lessen the impact on those who need this service and not discourage the utilization of the service." Requests rose sharply between 2010 and 2014, and the Department raised the fee to $2,350 to match a cost-of-service study, extending that amount in 2015 to certificate requests arising from the other expatriating acts as well. In a final rule published March 13, 2026 and effective April 13, 2026, the fee returned to $450. The Department cited both the public's concerns about the cost and the tax-related difficulties Americans abroad encounter, in part because of the reporting requirements FATCA places on foreign financial institutions. The change was not made retroactive and the Department declined to refund the $1,900 difference to people who had already paid.
The Certificate of Loss of Nationality is the document that proves it, and the IRS gets a copy. If the Department approves, it issues a Certificate of Loss of Nationality and, under 22 CFR 50.50(b), copies go to the immigration authorities and to the person concerned. Internal Revenue Code section 6039G(d)(2) separately requires the Secretary of State to give the IRS a copy of every approved certificate, and 6039G directs the Treasury Secretary to publish in the Federal Register, within 30 days after the close of each calendar quarter, the name of each individual losing US citizenship. That quarterly list is why renunciations are publicly countable.
The burden of proof runs against the person claiming the loss happened. Section 1481(b) provides that where loss of nationality is put in issue, the burden is on the party claiming that the loss occurred, to establish it by a preponderance of the evidence. It also presumes that anyone who performed an expatriating act did so voluntarily, a presumption that can be rebutted by the same standard. In practice this matters most to someone trying to establish that a past act, such as naturalizing elsewhere decades ago, already ended their citizenship.
What renunciation does not do. It does not settle tax. US tax attaches to citizenship, so renouncing ends the obligation prospectively, but returns and reports for years already lived as a citizen remain due, and a separate expatriation tax applies to people who meet certain income, net-worth or compliance tests on the way out. It does not restore itself either: US law provides no general route back, so a renunciation should be treated as permanent. And it does not create a right to live anywhere. A person who renounces without holding another nationality becomes stateless, which is why posts raise the point during the interviews.
