Denaturalization Process Explained: Step-by-Step Guide 2026

DOJ Denaturalization: Complete 2026 Guide to Citizenship Revocation

DOJ denaturalization is the legal process the U.S. Department of Justice uses to revoke the citizenship of naturalized Americans who illegally procured their naturalization or obtained it through concealment of a material fact or willful misrepresentation. The DOJ filed at least 105 civil denaturalization lawsuits in the first seven months of 2026 — an all-time record. The process requires a federal court order; citizenship cannot be revoked administratively.

Quick Facts

What Is DOJ Denaturalization?

DOJ denaturalization is the process by which the U.S. Department of Justice asks a federal court to revoke a naturalized citizen’s U.S. citizenship and cancel their Certificate of Naturalization. It is not a criminal prosecution in most cases — it is a civil enforcement action filed in federal district court. The government must prove that the person’s naturalization was illegally procured or procured by concealment of a material fact or by willful misrepresentation.

Under the Immigration and Nationality Act, a naturalized U.S. citizen’s citizenship may be revoked if the naturalization was illegally procured or procured by concealment of a material fact or by willful misrepresentation. The government bears the burden of proof, and the case must be decided by a federal judge — not by USCIS or DHS alone.

Denaturalization is distinct from deportation. Citizenship generally must be stripped first through a successful denaturalization action before removal proceedings can occur. Immigration lawyers often describe denaturalization as the “gateway to deportation” rather than deportation itself.

Who Is at Risk of Denaturalization?

You are at risk of denaturalization if the government can prove that you concealed or misrepresented a material fact during your naturalization process, or that you were legally ineligible for citizenship at the time you naturalized. The risk is not based on crimes committed after naturalization — it is based on pre-naturalization conduct that was not disclosed and later discovered.

Who qualifies for targeting:

• Naturalized citizens who failed to disclose criminal conduct that occurred before naturalization

• Naturalized citizens who lied on Form N-400, Application for Naturalization

• Naturalized citizens who were ineligible for naturalization because they lacked “good moral character” at the time of naturalization

• Naturalized citizens who obtained citizenship through immigration fraud

• Naturalized citizens who concealed prior removal orders, criminal convictions, or terrorist affiliations

Who does NOT qualify for targeting:

• U.S.-born citizens (denaturalization does not apply to native-born citizens)

• Naturalized citizens whose post-naturalization crimes are unrelated to any pre-naturalization conduct

• Naturalized citizens who made minor, non-material errors on their applications

• Naturalized citizens whose applications were fully accurate and truthful

Common exceptions and limitations:

The Supreme Court has held that district courts lack equitable discretion to refrain from entering a judgment of denaturalization once the government establishes that citizenship was procured illegally or by concealment or misrepresentation. This means that if the government proves its case, the judge must order denaturalization. However, the government must meet a high burden of proof, and the conduct must relate to the time of naturalization, not afterward.

Legal Grounds for Denaturalization

There are three primary legal grounds for denaturalization under 8 U.S.C. § 1451(a):

1. Illegally procured naturalization. This applies when the person was not legally eligible for citizenship at the time of naturalization. Examples include lacking lawful permanent resident status, failing the continuous residence requirement, or lacking the required good moral character.

2. Concealment of a material fact. This applies when the person hid information that would have disqualified them from citizenship. Examples include failing to disclose a prior criminal conviction, concealing a prior removal order, or hiding terrorist affiliations.

3. Willful misrepresentation. This applies when the person made false statements during the naturalization process. Examples include lying about criminal history on Form N-400 or providing false testimony under oath to a USCIS officer.

According to the ABA Tax Times, denaturalization proceedings most commonly arise from false statements made during the naturalization process, particularly on Form N-400. The form asks whether the applicant has “EVER . . . committed a crime . . . for which you were NOT arrested” — and denaturalization cases frequently involve applicants who answered “no” despite having engaged in criminal conduct prior to naturalization that later resulted in a conviction.

The Denaturalization Process: Step-by-Step

The denaturalization process involves three distinct phases: investigation, litigation, and immigration consequences.

Phase One: Government Investigation

The process typically begins when USCIS, DHS, DOJ, or another agency identifies information suggesting that citizenship may have been unlawfully obtained. Potential triggers include:

• Criminal investigations and convictions

• Immigration fraud investigations

• National security investigations

• Audits of prior immigration files

• Information received from foreign governments

• Inconsistent statements in later immigration filings

Agencies increasingly rely on digital records, database matching, and interagency information sharing to identify potential cases. USCIS monitors criminal proceedings involving naturalized citizens and compares fingerprint records to identify matches.

Phase Two: Denaturalization Litigation

The government files a denaturalization action in federal district court. At this stage, the person remains a U.S. citizen, remains entitled to constitutional protections, and the government bears the burden of proof. The case proceeds as a civil lawsuit, and the defendant has the right to counsel, the right to present evidence, and the right to appeal an adverse decision.

Phase Three: Immigration Consequences

Only after citizenship is revoked do immigration consequences become possible. The individual may return to whatever immigration status existed before naturalization — or may be left without lawful status. At that point, DHS may seek removal. In some cases, the individual may revert to lawful permanent resident status; in others, the government may argue that the green card was fraudulently obtained and that lawful permanent residence never legally existed.

2026 Denaturalization Statistics

The DOJ has dramatically expanded denaturalization filings in 2026. In July 2026 alone, at least 50 denaturalization complaints were filed — an all-time high — bringing the total for the first seven months of 2026 to at least 105 lawsuits.

Key statistics:

The DOJ announced on October 5, 2026, that it had filed denaturalization actions against 40 individuals between August 21 and October 2, 2026 — the largest volume of complaints submitted in a single period under the Trump administration. Attorney General Todd Blanche said: “Today’s announcement marks the largest denaturalization effort in modern history”.

Who Has Been Targeted in 2026?

The individuals targeted in 2026 denaturalization cases include people convicted of serious offenses, including:

• Espionage: Two individuals accused of acting as agents for a foreign government

• Child sexual abuse: Multiple cases involving child pornography and sexual abuse of minors

• Money laundering: Individuals convicted of conspiracy to commit money laundering

• Healthcare fraud: A Medicare fraudster who submitted over $886,000 in false claims

• Drug trafficking: Individuals convicted of conspiracy to distribute cocaine

• Immigration fraud: Individuals who concealed prior criminal convictions or removal orders

Cases have been filed in multiple districts, with the highest concentrations in Florida (49 total cases since 2008), California (26), Texas (16), and Georgia (13).

Recent Changes in Denaturalization Policy

The Trump administration has made denaturalization a top civil enforcement priority through multiple policy changes.

June 2025 Civil Division Enforcement Priorities Memo. The DOJ issued an internal memo directing prosecutors to “prioritize and maximally pursue denaturalization proceedings in all cases”.

December 2025 USCIS guidance. The administration issued internal guidance asking USCIS field offices to prepare 100–200 denaturalization cases per month for the remainder of FY2026.

January 2025 executive order. President Trump issued an executive order requiring the Secretary of State, in coordination with the Attorney General and DHS, to “ensure the devotion of adequate resources to identify and take appropriate action for offenses described in 8 U.S.C. § 1451”.

IRS–ICE data-sharing agreement. The 2025 data-sharing agreement between the IRS and ICE has expanded interagency information sharing, heightening compliance risks for naturalized citizens with tax issues.

Denaturalization vs. Deportation: Key Differences

Practical Examples: Who Faces Risk?

Naturalized citizen with an old criminal conviction. A person who was convicted of a misdemeanor before naturalizing but answered “no” to the criminal history question on Form N-400 may face denaturalization if the government discovers the conviction. The relevant conduct occurred before naturalization, even if the conviction came later.

Naturalized citizen who used a different name. A person who entered the U.S. under one identity, was ordered removed, and later naturalized under a different identity may face denaturalization. This was the pattern in Operation Janus cases, which identified about 315,000 cases where fingerprint data was missing from the centralized digital repository.

Naturalized citizen with post-naturalization conviction. A person convicted of a crime after naturalization is generally not at risk of denaturalization unless the government can prove that the underlying conduct occurred before naturalization and was concealed. The ABA Tax Times emphasizes that denaturalization is not based on crimes committed after naturalization.

Family of 4 with a naturalized parent. Denaturalization of one person does not automatically strip immigration status from a spouse or children. However, complications may arise if the spouse’s immigration benefits depended on fraud allegedly committed by the naturalized person.

Senior receiving SSI who naturalized decades ago. A naturalized citizen who has been a U.S. citizen for decades and has no criminal record or fraud in their immigration history faces very low risk. The government has stated it is targeting serious cases involving fraud and concealment.

Disabled worker who naturalized through a family petition. If the person’s naturalization was lawful and no material facts were concealed, they face no risk. Denaturalization requires proof of illegal procurement or fraud.

College student who naturalized as a child. Derivative citizens who acquired citizenship through a parent’s naturalization are generally not subject to denaturalization based on their own conduct, though the parent’s fraud could theoretically affect the derivative citizenship claim.

Veteran who naturalized through military service. Naturalized veterans face the same legal standards as other naturalized citizens. If their naturalization involved fraud or concealment, they could be targeted; otherwise, they face no risk.

Defenses Against Denaturalization

If you are targeted for denaturalization, you have legal defenses. The government must prove its case by clear, unequivocal, and convincing evidence — a higher standard than in most civil cases.

Common defenses include:

1. The statement was not material. The concealed fact must have been material to the naturalization decision. If the government would have granted citizenship anyway, denaturalization may not apply.

2. The statement was not willful. The misrepresentation must have been made knowingly and intentionally, not through mistake or misunderstanding.

3. The conduct occurred after naturalization. Denaturalization is not based on post-naturalization crimes. If the conduct occurred after citizenship was granted, it cannot support denaturalization.

4. The person was actually eligible. If the person was legally eligible for citizenship despite the concealed fact, the government may not be able to prove illegal procurement.

5. Lack of evidence. The government bears the burden of proof. If the evidence is insufficient to meet the clear and convincing standard, the case should be dismissed.

6. Statute of limitations for criminal denaturalization. While civil denaturalization has no statute of limitations, criminal denaturalization under 18 U.S.C. § 1425 is subject to a statute of limitations.

Common Mistakes and Misunderstandings

Mistake 1: Thinking denaturalization is automatic. Denaturalization requires a federal court order. USCIS cannot revoke citizenship on its own.

Mistake 2: Assuming only criminals are targeted. While many cases involve criminal conduct, denaturalization can also apply to non-criminal fraud or misrepresentation.

Mistake 3: Believing there is a statute of limitations. There is no statute of limitations for civil denaturalization. Cases have been filed against people who naturalized decades ago — some as far back as 1978.

Mistake 4: Confusing denaturalization with denaturalization quotas. The administration has set a goal of 100–200 cases per month, but this is a target, not a legal requirement. Cases must still meet the legal standard.

Mistake 5: Thinking naturalized citizens have no rights. Naturalized citizens facing denaturalization retain constitutional protections, the right to counsel, and the right to appeal.

Frequently Asked Questions

Can a naturalized citizen be deported without denaturalization?

No. Under U.S. law, citizenship generally must be stripped first through a successful denaturalization action before removal proceedings can occur. Denaturalization is the gateway to deportation, not deportation itself.

Does denaturalization affect my Social Security benefits?

If you are denaturalized, your eligibility for Social Security benefits may be affected depending on your immigration status after denaturalization. If you revert to lawful permanent resident status, you may retain eligibility. If you lose all lawful status, benefits may be terminated. Consult an immigration attorney.

How long does denaturalization take?

The investigation phase can take years. Once a complaint is filed, litigation typically takes 1–3 years. There is no statute of limitations for civil denaturalization, so cases can be filed decades after naturalization.

Can I lose my citizenship for a crime committed after naturalization?

Generally, no. Denaturalization is based on pre-naturalization conduct that was concealed or misrepresented. A post-naturalization conviction may support denaturalization only if it relates to conduct occurring before citizenship was granted.

What happens to my family if I am denaturalized?

Denaturalization of one person does not automatically strip immigration status from a spouse or children. However, complications may arise if family members’ immigration benefits depended on the fraud. Consult an immigration attorney.

Can I appeal a denaturalization order?

Yes. A denaturalization order can be appealed to the U.S. Court of Appeals for the circuit where the case was heard. The appellate court reviews the district court’s legal conclusions and factual findings.

Does denaturalization apply to U.S.-born citizens?

No. Denaturalization applies only to naturalized citizens. U.S.-born citizens cannot be denaturalized.

What is Operation Janus?

Operation Janus was a DHS initiative established in 2010 that identified about 315,000 cases where fingerprint data was missing from the centralized digital fingerprint repository. Some of these cases involved people who may have circumvented background checks during naturalization. The initiative largely ceased after approximately 167,000 records were digitized and funding ran out.

How many denaturalization cases were filed in 2025?

The DOJ won eight of the 13 denaturalization cases it brought in 2025. The total number of cases filed in 2025 was higher than in any single year during Trump’s first term.

Is denaturalization political?

The Trump administration has framed denaturalization as a national security and integrity measure. Critics argue it is being used as an immigration enforcement tool and could have a chilling effect on naturalized citizens and eligible-to-naturalize populations. The legal standard remains the same regardless of political context.

What should I do if I receive a denaturalization complaint?

Contact an immigration attorney immediately. Do not ignore the complaint. You have the right to respond, present evidence, and defend your citizenship in federal court. Deadlines are strict, and failure to respond can result in a default judgment.

Can denaturalization make me stateless?

It can. If a person is denaturalized and has no other nationality, they may become stateless. Human rights groups have raised concerns about this consequence, particularly for people who renounced their original citizenship to become U.S. citizens.
