(MINNESOTA) — The federal government’s renewed interest in denaturalization in connection with a major Minnesota public benefits fraud investigation highlights a hard legal limit: U.S. citizenship can be revoked only when the government proves that the person obtained naturalization unlawfully—typically by “illegal procurement” or willful, material misrepresentation tied to eligibility.
That distinction matters because many high-profile fraud cases involve conduct that occurred after someone became a U.S. citizen. Post-naturalization criminality, standing alone, usually is not enough. Denaturalization requires a tighter nexus to the naturalization process itself, and courts apply demanding proof rules.

What the government appears to be weighing in Minnesota
Federal authorities have publicly linked immigration consequences to wide-ranging pandemic-era fraud investigations in Minnesota, including the “Feeding Our Future” case and alleged irregularities in childcare assistance funding. Public statements referenced denaturalization as a possible tool for individuals convicted in these schemes.
From a legal standpoint, that announcement is not the same as a denaturalization judgment. Denaturalization is typically decided in federal court, and the government must satisfy specific statutory elements under INA § 340 (8 U.S.C. § 1451) and related case law.
The controlling legal standard: “Illegal procurement” or material misrepresentation
The statute most associated with civil denaturalization is INA § 340(a). It authorizes the government to file suit to revoke naturalization that was “illegally procured” or procured “by concealment of a material fact or by willful misrepresentation.”
In practice, civil denaturalization cases often track two theories:
- Illegal procurement: The person was not eligible for naturalization at the time it was granted.
- Fraud or misrepresentation: The person obtained naturalization by lying or hiding a material fact that affected the adjudication.
Although denaturalization is primarily litigated in federal district court, immigration precedent on material misrepresentation often informs related eligibility questions across the system. A frequently cited formulation appears in Matter of S- and B-C-, 9 I&N Dec. 436 (BIA 1961; A.G. 1961), which treats a misrepresentation as “material” when it tends to shut off a line of inquiry relevant to eligibility.
That “line of inquiry” concept shows why Minnesota’s fraud prosecutions could matter in immigration terms only if the underlying conduct connects to immigration benefits, admissibility, good moral character, or the truthfulness of prior filings.
Key facts that could create (or defeat) a denaturalization theory
Public reporting and official statements describe fraud allegations involving shell entities, misused program funds, and money laundering during the COVID-19 period. Those allegations, even if proven, do not automatically translate to denaturalization for naturalized citizens.
The government would typically need facts such as:
- The person misstated criminal conduct or omitted arrests, charges, or material facts on the N-400 naturalization application.
- The person lied about prior immigration history, including prior marriages, identities, residence, or entries.
- The person lacked good moral character during the statutory period but concealed disqualifying conduct. See INA § 316(a) (general naturalization), INA § 101(f) (good moral character), and 8 C.F.R. § 316.10.
- The person obtained citizenship through a prior immigration benefit that was itself secured by fraud, and that fraud made the person ineligible to naturalize.
Crucially, many financial crimes occur outside the “statutory period” for good moral character. For most applicants under INA § 316(a), that period is generally five years before filing, plus up to the oath. That timing issue can limit denaturalization theories based only on later wrongdoing.
Warning: A conviction can be relevant even if it happens after naturalization, but denaturalization still requires proof that citizenship was unlawfully obtained at the time it was granted.
What Supreme Court case law requires
The Supreme Court has repeatedly emphasized caution because citizenship is a weighty status. Two decisions often drive modern analysis:
- Kungys v. United States, 485 U.S. 759 (1988): addresses materiality and the government’s burden in civil denaturalization.
- Maslenjak v. United States, 582 U.S. 335 (2017): in the criminal denaturalization context under 18 U.S.C. § 1425, the Court required a causal connection between the illegal act and the procurement of citizenship.
These cases support a core point relevant to the Minnesota discussion: proving that someone committed fraud against a government program is not identical to proving that the person procured citizenship by fraud.
Civil vs. criminal paths: different tools, overlapping consequences
Denaturalization can be pursued in at least two ways:
- Civil denaturalization under INA § 340 (8 U.S.C. § 1451).
- Criminal prosecution for unlawful procurement of citizenship under 18 U.S.C. § 1425, which can lead to loss of citizenship upon conviction.
- Civil denaturalization uses a high burden of proof and extensive litigation.
- Criminal cases require proof beyond a reasonable doubt, but they also require the statutory nexus described in Maslenjak.
Once a person is denaturalized, DHS may place them in removal proceedings if they lack another lawful status. That later step is handled in Immigration Court under the INA.
Warning: Denaturalization can trigger a second wave of risk. That includes removal, detention, and loss of derivative benefits for some family members.
How this may affect future cases beyond Minnesota
Even if only a small number of denaturalization filings result, policy emphasis can affect a wider group of people. In many cases, the practical impact shows up earlier than any courtroom judgment.
1) More record review across benefit applications
– USCIS and DHS may review older immigration filings for inconsistencies.
– That includes visa applications, adjustment of status submissions, asylum filings, or prior petitions.
– Discrepancies that were once treated as minor can become central in fraud-based inquiries.
2) Naturalization applicants may face tougher screening
– Expect more requests for evidence and more detailed questioning about organizations, taxes, and prior addresses.
– Closer review of selective service, child support, and criminal history is likely.
3) Spillover to students and workers
– For F-1 students and H-1B workers, the Minnesota focus underscores a compliance reality.
– Fraud findings in any federal program can generate immigration scrutiny at visa renewal, adjustment, or future naturalization.
Deadline note: If you receive a Notice to Appear (NTA) for Immigration Court, act quickly. Hearing dates and filing deadlines can be short, and missing them can have severe consequences.
Are there circuit splits?
Denaturalization is federal litigation, and approaches can vary by circuit on issues like materiality framing and evidentiary rulings. However, Kungys and Maslenjak supply nationwide guardrails that generally reduce large doctrinal splits on the central “nexus” question.
That said, outcomes still vary with local practice, the assigned judge, and the government’s evidence. Denaturalization cases are unusually fact-driven.
Any dissents to watch?
There is no single “Minnesota denaturalization case” decision yet in the public record in the way there would be with a published BIA precedent. The notable dissents in the legal backdrop tend to come from Supreme Court debates over how strictly to read causation and materiality.
The key practical takeaway from those debates is consistent: denaturalization is not supposed to be a shortcut punishment for unrelated crimes. The government must prove unlawful procurement of citizenship.
Practical takeaways for naturalized citizens and applicants
- Assume past filings matter. If you filed anything with USCIS or DOS, those statements can be compared to later submissions.
- Do not guess on forms. If you are unsure about an arrest disposition, travel dates, or prior names, get records first.
- Treat program-fraud allegations as immigration-sensitive. Even if the conduct is not immigration fraud, it can trigger broad agency review.
- If approached by agents, get counsel. You may have the right to remain silent in criminal investigations. Seek immigration counsel before interviews.
- If you are already a citizen, do not assume you are “immune.” Denaturalization is rare, but it is legally available where unlawful procurement is provable.
Strong consultation point: Anyone contacted about a fraud investigation, asked about prior immigration filings, or threatened with denaturalization should consult both criminal defense counsel and a qualified immigration attorney. Coordination matters, because statements made in one forum can affect the other.
