Sometimes—but not automatically. Whether you still have, or can regain, your former citizenship depends on the former country’s nationality law and on how that citizenship ended. Revocation by the country that naturalized you is a separate legal event; it does not, by itself, decide your status under another country’s law.
What happens to your former citizenship when naturalization is revoked?
There are two questions to resolve separately: what the naturalizing country’s revocation does to your status there, and what the former country’s law says about your earlier citizenship. Your former citizenship may have continued, may have ended, or may be recoverable only through a separate application. The answer depends on the laws of both countries and your individual history.

Start by establishing whether you actually lost the former citizenship. A person who never completed an effective renunciation—or whose former country did not treat the relevant act as ending citizenship—may be in a different position from someone whose citizenship ended formally or automatically under that country’s law. The fact that a later naturalization was revoked does not settle which situation applies.

- Both countries: Identify the country that naturalized you and the country of your former citizenship. Their laws answer different parts of the question.
- How the former citizenship ended: Find out whether you signed a renunciation, whether it was accepted or registered, or whether citizenship was lost automatically under the former country’s law.
- Dates and legal effect: Establish when any renunciation or loss took effect, and the grounds, finality, and effective date of the later revocation.
- Available route: Check whether the former country allows a person in your circumstances to resume, restore, register for, or newly apply for citizenship. Such procedures can depend on the reason and date of loss.
- Family status: Treat any effect on a spouse or child as a separate legal question; a person’s outcome does not automatically establish a family member’s status.
Gather the original naturalization and revocation papers, any renunciation documents, and the former country’s records of your citizenship. A qualified lawyer familiar with nationality law in both countries can help determine which rules apply; this is not a question with a reliable worldwide yes-or-no answer.
What does the U.S. example show?
Revocation of U.S. naturalization is not the same as losing another citizenship
Under 8 U.S.C. § 1451(a), U.S. attorneys may bring proceedings to revoke and set aside a naturalization order and cancel its certificate where the order and certificate were illegally procured or obtained through concealment of a material fact or willful misrepresentation. For revocation under that subsection, the statute says the action is effective as of the original order and certificate. The provision also contains other grounds and rules, so the subsection relevant to a particular case matters.
That U.S. rule determines the effect of the relevant U.S. revocation; it does not require another country to restore citizenship. The former country’s own law still governs whether its citizenship survived, ended, or can be reacquired.
Do not confuse denaturalization with voluntary expatriation
8 U.S.C. § 1481 addresses specified voluntary acts that result in loss of U.S. nationality when performed with the intention of relinquishing it. That is a distinct legal question from a court’s revocation of naturalization under § 1451.
A narrow former-citizen route is not a general restoration remedy
8 U.S.C. § 1435 allows certain former U.S. citizens who lost citizenship in specified historical marriage-related circumstances to apply for naturalization under modified requirements. It is not a general procedure for people whose naturalization was later revoked under § 1451.
How do official country examples differ?
These examples illustrate why the result depends on the former country and the circumstances of loss; none establishes a universal rule.
| Country or source | What the official material establishes | What it does not establish |
|---|---|---|
| United States | 8 U.S.C. § 1451(a) provides for revocation in specified circumstances and makes revocation under that subsection effective as of the original naturalization order and certificate. | It does not require a former country to restore its citizenship. Section 1435 is limited to specified historical marriage-related cases. |
| United Kingdom | UK government information says an accepted renunciation results in a declaration that can be used to show the person is no longer British. Official staff guidance describes registration routes by which some people may reacquire British nationality if they meet statutory criteria. | The existence of a route does not establish eligibility for a particular person or make reacquisition automatic. |
| Australia | Australian Department of Home Affairs information lists particular historical cases in which people may resume Australian citizenship, tied to prior status and dates under earlier legislation. | Those rules do not establish an equivalent route in another country or for every former Australian citizen. |
| Canada | The Canadian Citizenship Act includes provisions concerning renunciation and revocation. | Those provisions do not establish that Canadian procedures match the U.S., UK, or Australian examples. |
For a country not covered here, check its current nationality law and official government guidance rather than inferring a result from another country’s process. In particular, distinguish a route to regain citizenship from a rule that says citizenship never ended in the first place.

This is different from losing a new citizenship after naturalization was completed. UNHCR Guidelines on Statelessness No. 5 (draft) address a person who renounces a former nationality during a naturalization process but ultimately is not naturalized. The draft says the former state should take all possible steps to assist the person in reacquiring their former nationality. This is draft guidance for that specific situation, not a universal guarantee or a rule deciding what happens after a completed naturalization is later revoked.

Quick Recap
What should you do next?
- Identify the legal status in each country. Obtain the final revocation decision and records showing whether the former country still recognizes you as a citizen.
- Trace the former citizenship’s ending. Locate any renunciation application, acceptance or declaration, registration, and the date it took effect; ask the former country’s relevant authority what its law treats as the loss event.
- Read the applicable revocation provision. Confirm the grounds, finality, and effective date under the naturalizing country’s law. In a U.S. case, do not assume every provision has the same scope as § 1451(a).
- Check the former country’s specific remedy. Look for rules on resumption, restoration, registration, or fresh naturalization and whether the reason and date of your loss fit them.
- Get advice on connected family questions. Ask separately about any derivative citizenship claims or effects on a spouse or child.
