Can Your U.S. Citizenship Be Revoked? Understanding Denaturalization Rights and Risks

Yes, U.S. citizenship can be revoked through a legal process called denaturalization, but only under specific circumstances and with significant constitutional protections. The government must prove in federal court that your citizenship was obtained illegally or fraudulently. This is not a common occurrence, but the Trump administration has announced plans in 2025 to pursue denaturalization cases more aggressively, targeting hundreds of naturalized citizens for potential citizenship revocation.

Understanding when and how citizenship can be stripped is critical for naturalized U.S. citizens. Unlike losing a green card, which can happen through abandonment or certain criminal convictions, U.S. citizenship offers much stronger protections. However, those protections are not absolute. The federal government can initiate denaturalization proceedings if it believes your citizenship was improperly obtained.

This article explains the legal grounds for denaturalization, the process the government must follow, your constitutional rights, and practical steps to protect yourself if you're concerned about your citizenship status.

What Is Denaturalization and How Common Is It?

Denaturalization is the legal process through which the federal government revokes someone's U.S. citizenship after it has been granted. This process requires filing a civil lawsuit in federal district court—the government cannot simply cancel your citizenship administratively through USCIS.

Historically, denaturalization has been relatively rare. Between 1990 and 2017, the government pursued an average of about 11 denaturalization cases per year. However, this changed significantly starting in 2018, when the Trump administration created a dedicated denaturalization task force within USCIS and the Department of Justice.

Recent Denaturalization Trends (2025)

The current administration has announced plans to expand denaturalization efforts substantially:

• Increased prosecutions: The administration aims to strip citizenship from hundreds of naturalized Americans
• Enhanced scrutiny: USCIS has implemented stricter review procedures for naturalization applications, particularly regarding "good moral character" determinations
• Broader targeting: While initial efforts focused on individuals with undisclosed criminal histories, the scope has expanded to include various alleged application irregularities

The government's authority to denaturalize citizens comes from Section 340 of the Immigration and Nationality Act (INA), 8 U.S.C. § 1451, which permits denaturalization when citizenship was "illegally procured" or "procured by concealment of a material fact or by willful misrepresentation."

What Are the Legal Grounds for Denaturalization?

The government can only revoke citizenship for specific reasons established by law, not for policy disagreements or political reasons. Understanding these grounds helps you assess your risk and know what the government must prove.

Fraud or Willful Misrepresentation

This is the most common basis for denaturalization. The government must prove that you:

• Made false statements on your naturalization application (Form N-400)
• Concealed material facts that would have affected your eligibility
• Acted willfully, meaning you knew the information was false or intentionally hid relevant facts

Examples include:

• Lying about criminal history or arrests
• Concealing previous marriages or divorces
• Providing false information about residence or physical presence
• Using a false identity or fraudulent documents
• Failing to disclose membership in prohibited organizations

Important: Simple mistakes or minor errors typically do not constitute fraud. The government must prove willful misrepresentation under 8 CFR § 340.1, not mere negligence or honest mistakes.

Illegal Procurement of Citizenship

This ground applies when you were never eligible for citizenship in the first place, even if you didn't commit fraud. Situations include:

• Ineligibility for the underlying green card: If your permanent residence was obtained through fraud, your subsequent citizenship is also invalid
• Failure to meet continuous residence requirements: If you actually didn't maintain continuous residence during the required period before naturalization
• Lack of good moral character: If you engaged in conduct during the statutory period that demonstrated lack of good moral character but USCIS didn't discover it

Membership in Prohibited Organizations

Under INA § 313, 8 U.S.C. § 1424, citizenship obtained by someone who was a member of the Communist Party or other totalitarian organizations within 10 years before naturalization can be revoked. This provision also applies to those who joined such organizations within five years after naturalization, as it raises a presumption that the applicant concealed or misrepresented their intentions.

Refusal to Testify Before Congress

Under INA § 340(c), 8 U.S.C. § 1451(c), citizenship can be revoked if within 10 years of naturalization you refuse to testify before Congress concerning subversive activities, provided the refusal is based on self-incrimination grounds.

Military Service Exemption Cases

If you obtained citizenship through military service but received an "other than honorable" discharge before completing five years of honorable service, your citizenship may be subject to revocation under INA § 329, 8 U.S.C. § 1440.

What Is the Denaturalization Process?

The government cannot simply cancel your citizenship—it must file a civil lawsuit in federal district court and prove its case. This requirement provides significant constitutional protections.

Step 1: Investigation and Evidence Gathering

USCIS and the Department of Homeland Security investigate potential denaturalization cases by:

• Reviewing naturalization files and comparing them to other government records
• Checking databases for criminal records, immigration violations, or security concerns
• Conducting interviews or requesting additional documentation
• Coordinating with FBI, ICE, and other agencies

You typically won't know about this investigation until the government files a lawsuit.

Step 2: Filing the Civil Denaturalization Lawsuit

The U.S. Attorney's Office files a complaint in federal district court, typically in the district where you reside. The complaint must specify:

• The legal grounds for denaturalization
• Specific facts supporting those grounds
• Evidence the government intends to present

You will be served with the complaint and summons, just like any civil lawsuit.

Step 3: Legal Proceedings and Your Defense

Once sued, you have the right to:

• Hire an attorney (though the government is not required to provide one)
• File an answer to the complaint
• Conduct discovery to obtain government evidence
• Present your own evidence and witnesses
• Challenge the government's proof at trial

Critical: The burden of proof depends on the circumstances. Under the Supreme Court's decision in Maslenjak v. United States, 137 S. Ct. 1918 (2017), the government must prove that:

1. You made a false statement or concealed a material fact
2. The false statement or concealment was willful
3. The truth would have mattered to your naturalization eligibility (materiality)

For cases filed within five years of naturalization, the government must prove its case by "clear, unequivocal, and convincing" evidence—a high standard approaching the criminal "beyond reasonable doubt" standard, as specified in 8 CFR § 340.2.

For cases filed more than five years after naturalization, the standard is "preponderance of the evidence"—meaning more likely than not, which is easier for the government to meet.

Step 4: Court Decision and Appeals

After trial, the federal judge issues a decision. If the government prevails:

• The court enters a judgment revoking your citizenship
• Your Certificate of Naturalization is canceled
• You revert to your previous immigration status (typically lawful permanent resident, if that status was valid)

You have the right to appeal the decision to the U.S. Court of Appeals and potentially to the Supreme Court.

What Are Your Constitutional Rights in Denaturalization Cases?

Naturalized citizens have strong constitutional protections that limit the government's denaturalization power. These protections have been reinforced by several Supreme Court decisions.

Due Process Rights

The Fifth Amendment guarantees due process before the government can deprive you of citizenship. This means:

• Right to notice of the charges against you
• Right to a hearing in federal court
• Right to present evidence and cross-examine witnesses
• Right to appeal an adverse decision

In Schneiderman v. United States, 320 U.S. 118 (1943), the Supreme Court emphasized that denaturalization is a "grave" matter requiring strict adherence to due process.

Burden of Proof on the Government

The government bears the burden of proving grounds for denaturalization—you don't have to prove your innocence. The Supreme Court in Maslenjak v. United States (2017) clarified that the government must prove causation: that the false statement or omission actually affected your eligibility for citizenship.

This means the government cannot revoke citizenship for immaterial lies. For example, if you lied about a minor traffic ticket that wouldn't have affected your naturalization eligibility, that misrepresentation alone cannot support denaturalization.

Equal Protection

The Fourteenth Amendment's equal protection guarantee means naturalized citizens generally have the same rights as native-born citizens. However, only naturalized citizens can face denaturalization—native-born citizens cannot lose their citizenship involuntarily except in extremely rare circumstances (such as committing treason or serving in a hostile foreign military).

No Retroactive Application

The government cannot denaturalize you based on laws or standards that didn't exist when you naturalized. Your eligibility is judged by the law in effect at the time you became a citizen.

Who Is at Risk for Denaturalization?

While any naturalized citizen can theoretically face denaturalization if the government discovers fraud, certain groups face heightened scrutiny in 2025.

High-Risk Categories

Based on current enforcement priorities, these individuals face increased risk:

1. Undisclosed Criminal History

• Failed to disclose arrests, charges, or convictions on Form N-400
• Particularly serious: crimes involving moral turpitude, controlled substances, or fraud
• Even dismissed charges should have been disclosed if they occurred

2. Immigration Violations Before Naturalization

• Worked without authorization before obtaining green card
• Violated visa terms or overstayed
• Made false claims to U.S. citizenship
• Engaged in immigration fraud to obtain green card

3. National Security Concerns

• Alleged connections to terrorist organizations
• Membership in organizations deemed threats to national security
• Providing material support to designated groups (even if unknowingly)

4. Identity Fraud

• Used false identity or documents to obtain green card or citizenship
• Assumed another person's identity
• Used multiple identities in immigration proceedings

5. Marriage Fraud

• Obtained green card through fraudulent marriage
• Later naturalized based on that permanent residence

Lower-Risk Situations

You face minimal risk if:

• You truthfully answered all questions on your naturalization application
• You disclosed all arrests, immigration violations, and relevant history
• You met all eligibility requirements for your green card and citizenship
• Any mistakes on applications were honest errors, not intentional misrepresentations

How Can You Protect Yourself?

Proactive steps can help protect your citizenship and prepare you if denaturalization proceedings are initiated.

Review Your Immigration History

Obtain copies of your complete immigration file through a Freedom of Information Act (FOIA) request to USCIS. Review:

• Your original naturalization application (Form N-400)
• Green card application materials (Form I-485 or immigrant visa application)
• All supporting documents submitted
• Interview notes and USCIS decisions

Compare these documents to your actual history. If you discover discrepancies or errors, consult with an immigration attorney immediately about whether corrective action is possible or advisable.

Maintain Documentation

Keep records that support your eligibility for citizenship:

• Tax returns from the years before naturalization
• Evidence of continuous residence and physical presence
• Documentation of disclosed arrests or legal issues
• Proof of good moral character (employment records, community involvement)

Address Outstanding Issues

If you have unresolved immigration issues, address them proactively:

• Old deportation orders: If you have an outstanding removal order from before naturalization that USCIS didn't know about, consult an attorney
• Undisclosed arrests: If you failed to disclose arrests, gather documentation about the incidents
• Name changes: Ensure all name changes were properly documented and disclosed

Know Your Rights

If contacted by USCIS or DHS about your citizenship:

• You have the right to remain silent: You don't have to answer questions without an attorney present
• You have the right to an attorney: Hire an immigration lawyer immediately
• Don't sign anything without legal advice
• Don't make new statements that could be used against you

Avoid New Immigration Violations

As a U.S. citizen, certain actions could trigger denaturalization investigations:

• Don't make false claims about your citizenship history
• Don't help others commit immigration fraud
• Don't engage in activities that could raise national security concerns
• Maintain accurate information with USCIS if you change your name or other biographical details

What Should You Do If You're Facing Denaturalization?

If you receive notice of a denaturalization lawsuit or investigation, take immediate action.

Step 1: Hire an Experienced Immigration Attorney Immediately

Denaturalization cases are complex federal litigation requiring specialized expertise. Look for an attorney who:

• Has experience with denaturalization defense
• Practices federal civil litigation
• Understands both immigration law and constitutional law
• Has handled cases in federal district court

Do not try to handle this yourself. The consequences of losing citizenship are too severe.

Step 2: Gather All Relevant Documents

Work with your attorney to compile:

• Complete immigration file from USCIS (obtained through FOIA)
• Criminal records, if any
• Evidence supporting your original application claims
• Documentation of any disclosed information
• Character references and evidence of community ties

Step 3: Understand Your Options

Your attorney will evaluate potential defenses:

• Lack of materiality: The false statement didn't affect eligibility
• No willfulness: Any errors were honest mistakes, not intentional
• Government cannot meet burden of proof: Insufficient evidence
• Statute of limitations: Case filed too late (though this rarely applies)
• Constitutional violations: Government violated your rights during the process

Step 4: Consider Settlement

In some cases, the government may offer to settle by allowing you to:

• Voluntarily relinquish citizenship and retain permanent residence
• Avoid a court finding of fraud
• Prevent criminal prosecution for immigration fraud

Whether to accept such an offer depends on your specific circumstances and should only be decided with legal counsel.

Step 5: Prepare for Litigation

If settlement isn't appropriate, prepare for trial:

• Participate in discovery
• Identify witnesses who can support your case
• Work with your attorney to develop trial strategy
• Understand the timeline (these cases can take 2-3 years)

What Happens If You Lose Your Citizenship?

If a court orders denaturalization, you revert to your previous immigration status—typically lawful permanent resident (green card holder).

Immediate Consequences

• Your Certificate of Naturalization is canceled
• You lose the right to vote
• You lose eligibility for U.S. passports
• You become subject to deportation for certain criminal convictions
• You may lose eligibility for certain federal benefits and jobs

Your Immigration Status

If your underlying green card was valid:

• You return to lawful permanent resident status
• You must carry your green card
• You're subject to all rules governing permanent residents
• You could face deportation proceedings if you have criminal convictions

If your green card was also obtained fraudulently:

• You may have no lawful status
• The government may initiate removal proceedings
• You could be deported to your country of citizenship

Possibility of Reapplying

Depending on the grounds for denaturalization, you might be able to:

• Maintain your permanent residence and eventually reapply for citizenship
• Fix the issues that led to denaturalization
• Demonstrate rehabilitation or changed circumstances

However, if you were denaturalized for fraud, you'll face an extremely high bar to naturalize again, as you must overcome the finding that you lack good moral character.

Common Questions About Denaturalization

Can the government denaturalize me for crimes committed after naturalization?

No, generally not. Denaturalization typically requires that the grounds existed at the time of naturalization. Crimes committed after you became a citizen usually cannot form the basis for denaturalization, though they might lead to criminal prosecution.

The exception is if post-naturalization conduct proves you lied on your application. For example, if you joined a terrorist organization within five years of naturalization, this could raise a presumption that you had such intentions when you applied and misrepresented them.

What if I made an honest mistake on my naturalization application?

Honest mistakes typically do not support denaturalization. The government must prove willful misrepresentation or concealment. If you can show that an error was unintentional—perhaps due to confusion, language barriers, or misunderstanding the question—this is a strong defense.

However, the line between "mistake" and "willful misrepresentation" can
