Can My Citizenship Be Revoked? Grounds, Process, and Impact

Whether your U.S. citizenship can be revoked depends on how you got it. If you were born a U.S. citizen, the government cannot take your citizenship away against your will; only your own voluntary act, done with the intent to give it up, can end it. If you became a citizen through naturalization, the government can strip your citizenship, but only by winning a lawsuit in federal court on specific statutory grounds.

If You Were Born a U.S. Citizen

The Supreme Court decided this question in 1967 in Afroyim v. Rusk, holding that Congress has no general power to strip citizenship without the citizen’s consent. The rule applies the same way whether you were born on U.S. soil or born abroad to American parents.

Federal law lists actions that can result in loss of citizenship, but every one of them requires that you acted voluntarily and with the specific intent to give up your nationality. The law presumes voluntariness once you perform one of the listed acts, but you can rebut that presumption, and the burden of proving loss of citizenship falls on whoever claims it happened.¹

The listed acts include formal renunciation before a U.S. diplomatic or consular officer abroad, becoming a naturalized citizen of another country after age 18, taking a formal oath of allegiance to a foreign government, serving as an officer in a foreign military, or serving in any foreign armed forces engaged in hostilities against the United States. Treason and related offenses against the U.S. can also cost you your citizenship, but only after conviction by a court. A separate provision allows renunciation inside the United States, but only during a declared state of war and only with the Attorney General’s approval.¹

Intent is the safeguard. Millions of Americans hold dual citizenship or swear ceremonial oaths abroad without losing their U.S. nationality, because they never intended to give it up. The government would have to prove that intent before your citizenship could be treated as lost.

If You Naturalized: Grounds for Denaturalization

Naturalized citizens are in a different position. The government can bring a proceeding, called denaturalization, on any of several grounds set by federal law.

Fraud or Willful Misrepresentation

The most commonly used ground is that citizenship was obtained by concealing a material fact or making a willful misrepresentation during the naturalization process. Typical examples are lying about or hiding a criminal record, prior immigration violations, or membership in a disqualifying organization.²

Illegal Procurement

Citizenship can also be revoked if it was “illegally procured,” meaning you were not actually eligible when it was granted. This can happen without any intentional deception. If it turns out you did not meet the residency requirement, physical presence requirement, or another statutory condition, the naturalization is treated as void from the start.²

Joining a Prohibited Organization Within Five Years

If, within five years of naturalizing, you join or become affiliated with an organization that would have disqualified you from citizenship in the first place, the law treats that as evidence you were not genuinely committed to the Constitution when you took the oath. The regulations identify several categories: the Communist Party, any party that advocates totalitarianism, and organizations that advocate overthrowing the U.S. government by force or violence.²³ The presumption is rebuttable, but without contrary evidence it alone can support revocation.

Dishonorable Military Discharge

If you obtained citizenship through military service and are later separated under other-than-honorable conditions before completing five years of honorable service, that separation alone is grounds to revoke the naturalization.⁴

Contempt for Refusing to Testify

A naturalized citizen who refuses to testify before a congressional committee about alleged subversive activities within ten years of naturalizing, and is convicted of contempt for that refusal, faces revocation on the theory that citizenship was obtained by hiding material facts.²

What Counts as a “Material” Lie

Not every inaccuracy on a naturalization application is enough. The Supreme Court has set a demanding standard for what counts as material.

In Kungys v. United States (1988), the Court held that a misrepresentation is material only if it had a natural tendency to influence the government’s decision on whether to grant citizenship. A lie about something irrelevant to your qualifications, even a deliberate one, does not clear that bar.⁵

The Court sharpened this in Maslenjak v. United States (2017). The government must show that the lie was about facts that would have mattered to an immigration official, either because those facts would themselves have justified denying the application, or because they would predictably have led an investigator to discover other disqualifying information. Where the government’s theory is that the lie derailed an investigation that would have uncovered something else, it has to prove both that the lie was relevant enough to trigger further inquiry and that the inquiry would predictably have turned up disqualifying evidence.⁶

Many denaturalization cases turn on this point. The government cannot simply point to a false answer on the N-400; it has to connect that answer to something that genuinely affected the outcome.

How the Denaturalization Process Works

Denaturalization is not something an immigration officer or agency can order on its own. The Department of Justice must file a civil lawsuit in federal district court. You receive formal notice of the complaint, you have the right to an attorney, and you can present evidence and cross-examine witnesses. Because it is a civil proceeding, there is no automatic right to a court-appointed attorney if you cannot afford one.

The government carries the burden of proof, and it is a heavy one. Since Schneiderman v. United States (1943), the standard has been “clear, unequivocal, and convincing” evidence, significantly higher than the “more likely than not” test used in ordinary civil cases. The Court set the bar deliberately, recognizing that citizenship is too important to take away on thin or ambiguous evidence.⁷

There is no statute of limitations on civil denaturalization. The government can file suit decades after you were naturalized. The five- and ten-year windows described above define specific triggering events, not the deadline for the government to sue. Criminal denaturalization under a separate statute does carry a ten-year statute of limitations, but the civil path has no such limit.

If the government meets its burden, a federal judge orders the naturalization revoked. The order is retroactive: it treats your citizenship as void from the date it was granted, not just from the date of the court’s ruling.² You can appeal to the U.S. Court of Appeals; because the federal government is a party, you have 60 days from entry of judgment to file the notice of appeal rather than the 30 days that applies in most civil cases.

What Revocation Means for You and Your Family

Once a court revokes your naturalization, you revert to whatever immigration status you held before you became a citizen, typically lawful permanent resident. That status is not guaranteed to hold, because the same facts that supported denaturalization, particularly fraud, can also be grounds for deportation. Removal proceedings can follow.

Family members can be affected too. If your citizenship is revoked because of fraud or misrepresentation, any spouse or child who derived citizenship through your naturalization loses it as well, whether they are inside or outside the United States.²

If the revocation is based on something other than fraud, such as joining a prohibited organization within five years or a dishonorable military discharge, derivative family members lose citizenship only if they are living outside the United States at the time. Those residing in the country keep their status.² And if the ground is illegal procurement alone, with no fraud, derivative family members do not lose their citizenship at all. Which ground the government uses to revoke one person’s citizenship can decide whether an entire family is affected.
