Yes, U.S. citizenship can be revoked, but the rules are narrow and the process is not casual. For naturalized citizens, the federal government can ask a court to cancel citizenship if it was obtained illegally or through fraud, or on a handful of other statutory grounds. For people born citizens, the Supreme Court has held that citizenship cannot be taken away against their will; it can only be lost by their own voluntary act. Everything else in the law flows from that split.
Why It Matters How You Became a Citizen
In Afroyim v. Rusk, the Supreme Court held that the Fourteenth Amendment protects “every citizen of this Nation against a congressional forcible destruction of his citizenship,” and that a citizen cannot lose that status “unless he voluntarily relinquishes” it.1Cornell Law School Legal Information Institute. Afroyim v Rusk, 387 US 253 If you were born on U.S. soil or born abroad to U.S. citizen parents, that ruling is your shield. No statute, agency, or court order can strip your citizenship without proof that you chose to give it up.
Naturalized citizens have the same protection against arbitrary revocation, but with one important difference. The government can go back and challenge whether the naturalization was valid in the first place. If a court finds it wasn’t, the citizenship is undone. That court process is called denaturalization, and it is where nearly all revocation cases live.
Grounds for Denaturalization
Federal law lists specific reasons the government can seek to revoke a naturalized citizen’s status. The case has to fit one of them.
Fraud, Concealment, or Illegal Procurement
This is by far the most common ground. Under 8 U.S.C. 1451, citizenship can be revoked if it was illegally procured or obtained through concealment of a material fact or willful misrepresentation.2Office of the Law Revision Counsel. 8 USC 1451 – Revocation of Naturalization Illegal procurement means the applicant didn’t actually qualify: not enough time as a lawful permanent resident, failure to meet the good moral character requirement, or some other missing eligibility piece. Concealment means the person hid something the officer would have wanted to know, like a criminal history or a false identity.
The government doesn’t have to prove the hidden fact would have automatically disqualified the applicant. It’s enough to show the lie kept the immigration officer from investigating properly. And there’s no statute of limitations on civil denaturalization. A case can be filed five years or fifty years after the oath.
Joining a Prohibited Organization Within Five Years
If a newly naturalized citizen joins certain organizations within five years of naturalization, the law treats that as evidence they weren’t genuinely committed to the Constitution when they took the oath. Unless the person can rebut it, that alone can support revocation.2Office of the Law Revision Counsel. 8 USC 1451 – Revocation of Naturalization The prohibited categories, set by federal regulation, include the Communist Party, other totalitarian parties, groups advocating a totalitarian dictatorship in the United States, and organizations classified as subversive.3eCFR. 8 CFR 313.2 – Prohibitions
Dishonorable Discharge After Military Naturalization
Noncitizens who naturalize through military service during designated periods of armed conflict must complete at least five years of honorable service. Separation under other-than-honorable conditions before hitting that five-year mark is grounds for revocation.4Office of the Law Revision Counsel. 8 USC 1440 – Naturalization Through Active-Duty Service in the Armed Forces The statute specifically excludes discharge as a noncitizen and discharge as a conscientious objector who refused any military duty. The military branch provides a certified discharge record, and USCIS refers these cases to Immigration and Customs Enforcement.5U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part I Chapter 7 – Revocation of Naturalization
Criminal Conviction for Unlawful Naturalization
A separate criminal statute, 18 U.S.C. 1425, makes it a crime to procure or attempt to procure naturalization contrary to law.6Office of the Law Revision Counsel. 18 USC 1425 – Procurement of Citizenship or Naturalization Unlawfully Penalties run up to 10 years for a first or second offense, up to 15 years for later offenses, up to 20 years if the fraud facilitated drug trafficking, and up to 25 years if it facilitated international terrorism. When someone is convicted under this statute, the court is required to revoke citizenship and cancel the naturalization certificate as part of the criminal judgment.2Office of the Law Revision Counsel. 8 USC 1451 – Revocation of Naturalization No separate civil suit is needed.
How a Denaturalization Case Works
Denaturalization is not handled by immigration courts or USCIS officers. The U.S. Attorney for the district where the naturalized citizen lives files a civil lawsuit in federal district court seeking to cancel the naturalization.2Office of the Law Revision Counsel. 8 USC 1451 – Revocation of Naturalization The person named in the suit gets at least 60 days’ notice, has the right to counsel, can conduct discovery, and gets a full trial. If the person has left the country or cannot be found in the district, the government can serve notice by publication.
The burden of proof is unusually heavy for a civil case. Federal prosecutors must present evidence that is “clear, unequivocal, and convincing,” a standard well above the “more likely than not” test in most civil litigation. Courts have long held that citizenship is too important to strip away on thin evidence, so any ambiguity works in the citizen’s favor. If the government meets that bar, the court issues an order revoking citizenship and canceling the naturalization certificate retroactively to the original date. A losing respondent can appeal to the applicable U.S. Court of Appeals and, in theory, petition the Supreme Court, though the Court rarely takes these cases.7United States Department of Justice. Justice Manual 4-7.000 – Immigration Litigation
How a Born Citizen Can Lose Citizenship
Because the government cannot force it, the only route for a natural-born citizen is voluntary. Under 8 U.S.C. 1481, both born and naturalized citizens can lose nationality by voluntarily performing certain acts with the specific intent to give up U.S. status.8Office of the Law Revision Counsel. 8 USC 1481 – Loss of Nationality by Native-Born or Naturalized Citizen Intent is the essential element. The government bears the burden of proving the person actually meant to give up citizenship; the act by itself is not enough.
Recognized expatriating acts include:
- Formally renouncing citizenship before a U.S. consular officer abroad
- Naturalizing in another country after age 18 with the intent to give up U.S. citizenship
- Serving in a foreign military that is fighting against the United States, or serving as an officer in any foreign military
- Taking a foreign government position that requires an oath of allegiance to that country, or holding any foreign government role after acquiring that country’s nationality
- Committing treason or attempting to overthrow the U.S. government by force
Getting a second passport or voting in a foreign election, by themselves, do not cost you U.S. citizenship. The government would have to prove those acts were done specifically to abandon American nationality, which is a hard case to make.
What Happens After Citizenship Is Revoked
Once revocation is final, the person loses every right tied to citizenship: voting, a U.S. passport, eligibility for federal benefits, and the right to live in the country without immigration status. They revert to whatever status they held before naturalization, usually lawful permanent resident. If the underlying green card was also obtained through fraud, that status can be challenged too, and the person may end up with no lawful status at all. That opens the door to removal proceedings. The Supreme Court has clarified, though, that revocation doesn’t retroactively make someone deportable for things they did while they were a citizen.
The effects can reach family members who derived citizenship through the person’s naturalization.2Office of the Law Revision Counsel. 8 USC 1451 – Revocation of Naturalization If revocation was for illegal procurement, spouses and children keep their citizenship regardless of where they live.9U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part L Chapter 3 – Effects of Revocation of Naturalization If it was for concealment or willful misrepresentation, derivative family members lose their citizenship whether they’re in the U.S. or abroad. If it was for prohibited-organization membership or a military discharge, derivative family members lose citizenship only if they’re living outside the United States at the time. A spouse or child who did nothing wrong can still be pulled into the consequences, which is one reason these cases tend to be fought hard.
