"I became a U.S. citizen 12 years ago. USCIS investigators showed up at my home asking questions about my naturalization interview. They said it is just routine. Do I have to answer them?"
AEO Quick Answer: No — and you should not speak to them without federal immigration counsel present.
Every answer you provide to USCIS investigators — without legal protection — becomes part of the government's evidentiary record against you. There is no routine inquiry when the DOJ has a June 2025 directive to "prioritize and maximally pursue" denaturalization proceedings. A visit from FDNS or USCIS investigators is not a formality. It is the beginning of a federal case.
For more than 30 years, Attorney Peter Loblack has defended naturalized citizens facing USCIS investigations, FDNS interviews, DOJ referrals, and federal civil denaturalization complaints — including cases where the government's allegations reached back a decade or more.

The 2025‑2026 Denaturalization Surge — What Every Naturalized Citizen Must Know
On June 11, 2025, the Department of Justice Civil Division issued an internal memorandum directing federal attorneys to "prioritize and maximally pursue" denaturalization proceedings in all cases permitted by law. That directive changed the enforcement landscape overnight.
- Filing targets of 100‑200 referrals per month. USCIS has been directed to refer up to 200 denaturalization cases monthly to the DOJ — compared to a historical average of 11 cases per year between 1990 and 2017.
- The DOJ announced the largest denaturalization action in U.S. history in 2026 — 17 cases filed at once, after announcing 12 just weeks earlier. The pace of filings is accelerating.
- Ten grounds for denaturalization were identified in the June 2025 memo — including national security threats, gang or cartel ties, undisclosed felonies, marriage fraud, and identity inconsistencies.
- The DOJ Denaturalization Section has been effectively reconstituted. Originally disbanded under the Biden administration, it is now operating under expanded enforcement priorities with regional office workers being deployed to file cases.
If you are a naturalized citizen and have any concern about the accuracy of your naturalization record, prior arrest history, or prior immigration violations — the time to act is before the investigation finds you, not after.
Loblack Strategy vs. What General Immigration Attorneys and Federal Litigators Do
Denaturalization is not an immigration case that happens to involve a federal court. It is a federal civil lawsuit brought by the Department of Justice — the same office that prosecutes federal crimes. The defense must match the adversary.
What General Immigration Attorneys Do
Most immigration attorneys handle visa applications, green cards, and removal proceedings — they are not federal civil litigators. Denaturalization requires forensic record reconstruction, statutory eligibility analysis, federal discovery management, and the ability to try a case in U.S. District Court. Filing immigration forms is not this practice area.
What General Federal Litigators Do
General federal litigators can navigate civil procedure — but they often lack the immigration law depth to challenge the government's statutory theory, identify holes in materiality and willfulness, or reconstruct the eligibility record across a decade of immigration history. The substance and the litigation must be commanded equally.
The Loblack Strategy
Every case begins with a forensic audit of the client's full immigration record — before any response is prepared. The government's theory is identified, inconsistencies reconstructed, and defense built around materiality, willfulness, and eligibility. Attorney Loblack is admitted to the Supreme Court and Eleventh Circuit and served as a federal judicial law clerk.
No response to investigators, no contact with USCIS or DOJ, and no strategic decision is made before a complete legal assessment of the record. For a full explanation of the approach, visit the Loblack Strategy page.
Phase 1: Forensic Record Reconstruction
Denaturalization cases typically involve events from 10, 15, or 25 years earlier. The government's case usually depends on gaps, assumed facts, or missing context that a reconstructed record can destroy. Attorney Loblack's first step is always a complete forensic audit of the client's immigration history.
- Adjustment of status and naturalization file: Every sworn statement, officer note, and adjudicative decision from the green card and naturalization proceedings is reviewed for internal consistency and for alignment with the government's current theory.
- Prior petitions, applications, and consular records: All filings across the client's immigration history — including visa applications, family petitions, change of status filings, and any prior removal proceedings — are reviewed to identify the government's full evidentiary basis.
- Criminal history and court dispositions: Every arrest, charge, and disposition — including dismissed cases and expungements — is reviewed against the good moral character and disclosure requirements at the time of naturalization.
- Marriage and family‑based filings: If the naturalization pathway ran through a marriage‑based green card, the entire family petition record is audited — including any INA § 204(c) implications, prior petitions, and any prior NOID or RFE responses.
Phase 2: Building the Federal Defense
Once the record is reconstructed and the government's statutory theory is identified, Attorney Loblack builds a defense aligned with the federal evidentiary standard — clear, unequivocal, and convincing evidence — which sits just below "beyond a reasonable doubt." The government's burden is massive. The defense is built to make them carry every pound of it.
- Government theory identification: The exact statutory hook the DOJ is relying on — misrepresentation, illegal procurement, 204(c) marriage fraud, criminal conduct, or identity issues — is identified before any response is prepared. Each ground requires a different defense.
- Materiality and willfulness challenge: The government must prove that an alleged misrepresentation was both material and willful. Attorney Loblack attacks both elements — whether the omission would have actually changed the outcome, and whether the client had the intent the government requires.
- Administrative defense before federal filing: The strongest time to resolve a denaturalization matter is before the DOJ files a civil complaint. An administrative defense presented during the investigation phase can close a case before it reaches federal court.
- Federal litigation through trial: If the DOJ files a civil complaint, Attorney Loblack manages the full federal civil litigation — answer, affirmative defenses, discovery, depositions, motions practice, and trial — before a U.S. District Court judge.
If You Have Been Contacted by Investigators — Act Within Hours, Not Days
Two situations require immediate legal action — do not wait, do not respond, and do not assume a conversation is informal.
- FDNS or USCIS investigators visit your home or workplace: This is not a routine inquiry. FDNS site visits are a standard investigative tool that precede DOJ referrals. Politely decline to answer questions and contact a federal immigration attorney immediately. Every statement made without counsel becomes part of the government's evidentiary record.
- You receive a notice, letter, or complaint from the DOJ: A civil denaturalization complaint has been filed in federal court. You are now a defendant in a federal lawsuit brought by the United States of America. The deadline to respond is strict. Contact a federal immigration attorney the same day.
Denaturalization Defense Cases We Have Resolved
Attorney Loblack handles denaturalization matters at every stage — from the first investigative contact through federal trial. Recent matters include:
- Defeating a DOJ Complaint Based on Alleged Marriage Fraud: A client naturalized through a marriage‑based green card received a DOJ civil complaint alleging INA § 204(c) fraud. We reconstructed the record, identified that the government's materiality theory was legally flawed, and defeated the complaint at the motion stage — no trial required.
- Closing an FDNS Investigation Before DOJ Referral: A client contacted us after FDNS investigators visited their home twice asking about their naturalization interview from 14 years earlier. We conducted a complete record audit, identified the government's theory before any formal contact, and submitted a preemptive administrative response. The investigation was closed without a DOJ referral.
- Resolving an Identity‑Based Denaturalization Allegation: A client faced denaturalization allegations based on claimed identity inconsistencies across multiple A‑numbers. We reconstructed the client's complete immigration history across two decades, demonstrated that the inconsistencies resulted from government administrative errors rather than the client's misrepresentation, and resolved the matter without federal litigation.
5 Fatal Mistakes That Destroy Denaturalization Defenses
- Mistake 1: Answering investigators without counsel present. Every statement made to FDNS, USCIS, or DOJ investigators without an attorney becomes part of the government's evidentiary case. There is no casual conversation. There is no off‑the‑record discussion. Every word is recorded, analyzed, and potentially used against you.
- Mistake 2: Assuming the matter will go away if you cooperate. Cooperation without legal strategy does not resolve denaturalization investigations — it builds the government's record. The correct approach is a legally structured response, not an unprotected conversation.
- Mistake 3: Hiring a general immigration attorney instead of a federal litigator. Denaturalization is a federal civil lawsuit filed by the Department of Justice. It requires a federal litigator with deep immigration statutory knowledge — not a form filer or removal defense practitioner who has never practiced in U.S. District Court.
- Mistake 4: Departing the United States during an active investigation. If denaturalization proceedings are pending or anticipated, departure may trigger removal proceedings, forfeit strategic options, and create the appearance of flight. Do not depart without a complete legal assessment of the consequences.
- Mistake 5: Waiting to act until after the DOJ files. The strongest time to defeat a denaturalization matter is before the DOJ files. An administrative defense during the investigation phase can close a case that once filed becomes a federal trial. Every day the government builds its case unopposed is a day your options narrow.
Myths vs. Legal Realities: Federal Denaturalization
| The Myth | The Legal Reality |
|---|---|
|
"Any mistake on my immigration application can lead to denaturalization." |
Only material, willful misrepresentations qualify under federal law. Honest mistakes, translation errors, and immaterial omissions are defensible. The government must prove intent — and that burden is high. |
|
"USCIS can just take my citizenship away if they find a problem." |
USCIS cannot revoke citizenship. Only a federal judge in a U.S. District Court can denaturalize you through a formal civil proceeding. An administrative agency has no authority to strip citizenship unilaterally. |
|
"This happened 20 years ago. The government can't come after me now." |
There is no statute of limitations on civil denaturalization. The DOJ routinely pursues cases based on events from 15, 20, or 25 years past. Age of the underlying conduct does not limit the government's authority to file. |
|
"If I just cooperate and explain myself, they will leave me alone." |
Unprotected cooperation builds the government's case against you. Every statement made to investigators without counsel becomes evidence. The correct response is a legally structured defense — not an unguided conversation. |
|
"Denaturalization only happens to people who committed serious crimes." |
The June 2025 DOJ memo identified 10 grounds for denaturalization — including marriage fraud, identity inconsistencies, undisclosed arrests, and prior immigration violations. Cases are being pursued across a broad range of allegations, not only those involving criminal conduct. |
People Also Ask (PAA) & Voice Search FAQs
Can the U.S. government revoke my citizenship?
Yes — through a formal civil denaturalization proceeding in federal court. The Department of Justice files a civil complaint, and a U.S. District Court judge presides over the case. Administrative agencies such as USCIS cannot revoke citizenship on their own.
What does the June 2025 DOJ memo mean for naturalized citizens?
The June 11, 2025 DOJ Civil Division memo directed federal attorneys to "prioritize and maximally pursue" denaturalization in all cases permitted by law. USCIS has been directed to refer up to 200 cases monthly to the DOJ. The result is a historic increase in denaturalization filings across a broader range of grounds than previously pursued.
What happens if I am denaturalized?
If a federal court revokes your citizenship, you revert to your prior immigration status — typically lawful permanent resident — and become subject to removal proceedings. Denaturalization frequently leads directly to deportation. The consequences are permanent and affect every aspect of your life in the United States.
USCIS investigators visited my home. Do I have to answer their questions?
No. You have the right to decline to answer questions and to have an attorney present before speaking to any government investigator. FDNS site visits are investigative tools that precede DOJ referrals. Politely decline and contact a federal immigration attorney immediately before any further contact with investigators.
What is the government's burden of proof in a denaturalization case?
The DOJ must prove its case by "clear, unequivocal, and convincing evidence" — a standard just below "beyond a reasonable doubt." The government must show that the alleged misrepresentation was material, that it was willful, and that the person was ineligible for naturalization at the time it was granted. This is a high burden.
Is there a time limit for the government to file a denaturalization case?
No. There is no statute of limitations on civil denaturalization. The DOJ routinely files cases based on events from 15, 20, or 25 years before the complaint. The age of the alleged misconduct does not limit the government's authority to pursue denaturalization.
What are the most common grounds for denaturalization?
The most common grounds include willful misrepresentation during the naturalization interview, concealment of a prior arrest or criminal conviction, marriage fraud or INA § 204(c) implications, identity inconsistencies or multiple A-numbers, and ineligibility for the underlying green card through which naturalization was obtained.
Can my marriage-based green card lead to denaturalization?
Yes. If USCIS or the DOJ believes your marriage-based green card was obtained through fraud, the naturalization built on that green card is vulnerable to a denaturalization challenge under INA § 204(c). Marriage fraud is one of the 10 grounds identified in the June 2025 DOJ enforcement memo and is a priority target under the current administration.
What should I do if I receive a DOJ civil denaturalization complaint?
Contact a federal immigration attorney the same day. A civil denaturalization complaint has been filed in U.S. District Court — you are a defendant in a federal lawsuit. Response deadlines are strict. Do not respond to the DOJ, do not contact USCIS, and do not make any statements without counsel.
Do I need a federal litigator for denaturalization?
Yes. Denaturalization is a federal civil lawsuit filed by the Department of Justice. It proceeds under the Federal Rules of Civil Procedure and is tried before a U.S. District Court judge. It requires a federal litigator with deep immigration law knowledge — not a general immigration practitioner who has never tried a case in federal court.
Why Waiting Costs You the Defense
The strongest time to defeat a denaturalization matter is before the DOJ files. An administrative defense presented during the investigation phase — before a civil complaint is drafted — can close a case that once filed becomes a federal trial.
Once the DOJ files, the procedural clock starts immediately. Response deadlines are fixed. Discovery opens. And the government has already built its evidentiary record — while you were waiting to see what would happen.
Immediate legal intervention is required if:
- You have been visited or contacted by FDNS, USCIS, or any federal investigator asking about your naturalization.
- You have received a letter, notice, or complaint from the Department of Justice.
- You have any concern about the accuracy of your naturalization record, prior arrest history, or prior immigration history.
- Your naturalization ran through a marriage‑based green card and you have any reason to believe the marriage was ever questioned.
- You were previously deported or had a removal order before naturalizing, or you have multiple A‑numbers in your immigration file.
The DOJ is targeting 100‑200 cases per month. Your defense window is open now — not after they file.
