The Denaturalization Machine: Inside the Trump Administration's Unprecedented Push to Revoke American Citizenship

Between 1990 and 2017, the U.S. Department of Justice filed an average of 11 denaturalization cases per year — civil actions in federal court seeking to strip naturalized Americans of their citizenship [1]. In late 2025, internal guidance from U.S. Citizenship and Immigration Services instructed field offices to refer 100 to 200 such cases per month to DOJ attorneys, a quota that would translate to 1,200 to 2,400 referrals annually [2]. The gap between those two numbers defines the most aggressive citizenship-revocation campaign the United States has ever attempted.

As of early June 2026, NPR has identified 34 publicly announced denaturalization cases filed or resolved by the DOJ under the current administration, including 11 completed revocations of citizenship [3]. The numbers remain far below the administration's stated ambitions, but the infrastructure being built — new referral pipelines, expanded priority categories, and earmarked personnel — signals an effort designed to accelerate.

What the Law Allows

Denaturalization — the legal process of revoking a naturalized citizen's U.S. citizenship — is governed by 8 U.S.C. § 1451 [4]. Under the statute, the government may seek to revoke citizenship if it was "illegally procured" or obtained through "concealment of a material fact or by willful misrepresentation." There is no statute of limitations [5].

Unlike deportation proceedings, which are handled by immigration judges employed by the DOJ, denaturalization cases are heard in federal district courts. The government bears the burden of proof and must meet a standard of "clear, convincing, and unequivocal evidence" — a bar the Supreme Court has described as among the highest in civil law [4][6].

A landmark 2017 Supreme Court decision in Maslenjak v. United States further tightened the standard. The Court held unanimously that only false statements "material" to the decision to grant citizenship can justify revocation — rejecting the government's argument that any lie during the naturalization process, however minor, was sufficient grounds [7]. Justice Elena Kagan wrote that the government's broader reading would give prosecutors "extraordinary" and effectively unchecked discretion over millions of naturalized citizens [7].

The Expanded Target List

A June 2025 memo from Assistant Attorney General Brett A. Shumate directed DOJ attorneys to "prioritize and maximally pursue denaturalization proceedings" and established 10 priority categories [8]. Some of these categories — terrorism links, war crimes, human trafficking — had been pursued under prior administrations. Others represent expansions.

The new priority categories include:

• Members of terrorist organizations or individuals deemed national security threats
• Individuals who committed torture, war crimes, or human rights violations
• Those who "further or have furthered the unlawful enterprise" of gangs, drug cartels, or transnational criminal organizations
• Naturalized citizens convicted of felonies who failed to disclose their criminal history during naturalization
• Sex offenders, including those convicted of offenses against children
• Individuals who committed financial fraud, including PPP (Paycheck Protection Program) and Medicare fraud
• Those who committed human trafficking offenses
• Any other cases DOJ deems "sufficiently important to pursue" [8][9]

The last category — a catch-all — has drawn particular concern from legal advocates. "That kind of open-ended language gives prosecutors enormous discretion," said one immigration attorney quoted by CBS News [1].

Among the 17 citizens targeted in the latest round of filings, several were convicted of violent crimes including sex offenses against children, while others were accused of immigration fraud or financial crimes [1]. The administration has framed these cases as the low-hanging fruit of a much larger pipeline: federal agencies have forwarded more than 2,600 potential cases to prosecutors since January 2025 [10].

The Quota System

The referral quotas represent a structural shift in how denaturalization is pursued. Previously, cases arose organically — flagged during other investigations or discovered during routine reviews. The new system reverses that dynamic, establishing production targets that USCIS field offices are expected to meet.

"Requiring monthly quotas that are 10 times higher than the total annual number of denaturalizations in recent years turns a serious and rare tool into a blunt instrument and fuels unnecessary fear and uncertainty for the millions of naturalized Americans," former USCIS official Sarah Pierce told NPR [2].

The administration defends the approach as overdue enforcement. A USCIS spokesperson stated that the agency will prioritize individuals who "unlawfully obtained U.S. citizenship" and pursue cases involving "those individuals lying or misrepresenting themselves during the naturalization process" [11]. USCIS has said that prior vetting measures were "wholly inadequate," with many applicants approved "who should not have been" [9].

Due Process and the Cost of Defense

Denaturalization is a civil proceeding, which means defendants do not have an automatic right to appointed counsel [5][6]. Those who cannot afford an attorney must represent themselves against DOJ litigators in federal court — a structural asymmetry that legal scholars argue falls disproportionately on low-income naturalized citizens.

The typical denaturalization case involves discovery, depositions, motions practice, and a federal trial — procedures that can stretch over years and cost tens of thousands of dollars in legal fees even for straightforward cases [5]. Defendants retain the right to challenge evidence and to appeal, and the proceedings do unfold before independent Article III judges rather than executive-branch immigration courts [3].

Daniel Kanstroom, a professor of law at Boston College who specializes in immigration, told NPR that based on the cases filed so far, "I'm not seeing a major surge of worrisome denaturalizations. To me, it's not at the level of an emergency" [3]. But he and other scholars have cautioned that the system's impact will depend on volume: if quotas are met, the sheer number of cases could overwhelm both defendants' ability to respond and courts' capacity to adjudicate them carefully.

One legal expert told NPR, "I certainly don't see an easy pathway for this administration to fast-track denaturalizations or do end runs around the judiciary" [3]. The question is whether the administration's goal is rapid success or sustained pressure.

The Statelessness Question

If denaturalization succeeds, the individual reverts to their prior immigration status — typically lawful permanent residence — and becomes subject to deportation [1]. But for some defendants, the consequences are more severe. Those who were brought to the U.S. as children, who have no citizenship in their country of birth, or whose birth country would not accept them face the prospect of statelessness — a condition that violates international norms established by the 1961 Convention on the Reduction of Statelessness [5].

U.S. law contains no explicit prohibition on rendering a person stateless through denaturalization, a gap that distinguishes it from several peer democracies [12]. The current caseload has not yet produced a high-profile statelessness case, but immigration advocates have flagged it as a growing risk as the target population expands beyond clear-cut fraud cases.

How the U.S. Compares to Peer Democracies

The United States is not alone in revoking citizenship, but its legal framework is unusually permissive in certain respects.

The United Kingdom has revoked citizenship from at least 373 individuals since 2006, more than Canada, France, Australia, and the Netherlands combined [13]. However, the UK's framework is constrained: revocations are carried out by the Home Secretary and are subject to judicial review, and post-2014 reforms narrowed the grounds primarily to national security and terrorism [13][14].

Canada briefly expanded its denaturalization powers in 2015 under the Harper government's Bill C-24, which allowed citizenship revocation for dual nationals convicted of terrorism. The law was repealed in 2017 by the Trudeau government [14]. Germany permits revocation only for individuals who obtained citizenship through fraud, and only within 10 years of naturalization — an explicit time limit that U.S. law lacks [12]. Australia introduced provisions to revoke citizenship from dual nationals engaged in terrorism but has used the power sparingly [14].

Twenty-two European countries allow denaturalization for terrorism or behavior contrary to national interest [12]. But most impose constraints absent from U.S. law: time limits, restrictions to dual nationals only, or explicit prohibitions on creating statelessness.

Resources and Trade-Offs

The January 2025 executive order that launched the denaturalization push directed the Attorney General, Secretary of Homeland Security, Secretary of State, and Director of National Intelligence to "ensure the devotion of adequate resources" to identify naturalization violations and pursue cases [15]. The One Big Beautiful Bill, signed into law in July 2025, committed $170.7 billion in additional funding for immigration-related enforcement across DHS and DOJ [16].

Specific budget allocations dedicated solely to denaturalization have not been publicly detailed. The DOJ's Office of Immigration Litigation, which handles these cases, has historically operated with limited staff. Scaling to handle hundreds or thousands of annual filings would require significant new hiring or reallocation from other enforcement priorities — including the existing immigration court backlog, which exceeded 3 million pending cases as of 2025 [15][16].

The cost per successful denaturalization case is not publicly tracked, but given the federal litigation involved — including discovery, trial, and appeals — estimates based on comparable federal civil litigation suggest costs of $100,000 or more per case for the government, exclusive of judicial resources [5][6].

The National Security Argument

The administration's strongest cases involve individuals with clear ties to terrorism, war crimes, or serious violent offenses who concealed those histories during naturalization. The Center for Immigration Studies, which favors lower immigration levels, has argued that naturalization fraud represents a genuine national security gap, pointing to historical cases where individuals with ties to terrorist organizations obtained citizenship through misrepresentation [9].

Representative Tom Emmer introduced the SCAM Act in 2025 to expand denaturalization authority for "fraudsters, terrorists, and felons," framing the legislation as closing loopholes that allow dangerous individuals to shelter behind citizenship obtained through deception [17].

Critics do not dispute that fraud-based denaturalization is legally justified in individual cases. The debate centers on proportionality. The Brennan Center for Justice has argued that the administration's approach "will run into significant legal hurdles" because the Supreme Court has "firmly established limits" on using denaturalization as a broad enforcement tool, and that those limits are "deeply rooted in protections guaranteed by the 1st and 14th Amendments" [6].

The Conversation, an academic media outlet, reported that the DOJ's effort "could face widespread judicial pushback," with federal courts likely to apply strict scrutiny to cases that appear to stretch beyond proven fraud [18]. The administration's own track record suggests the constraints are real: despite setting quotas of 100 to 200 referrals per month, the DOJ had filed only 34 cases as of June 2026, with 11 successful revocations [3].

The Gap Between Rhetoric and Reality

The distance between the administration's stated targets and actual filings is the central tension of the denaturalization campaign. The infrastructure is being built for a mass-scale effort: referral pipelines, expanded priority categories, USCIS field office quotas. But the legal system through which these cases must pass — federal courts, the "clear and convincing" evidence standard, the Maslenjak materiality requirement, and defendants' appeal rights — functions as a brake.

NPR's review of filed cases found them "narrower than the rhetoric suggests" [3]. The Asian Law Caucus and other advocacy organizations have warned that the campaign's psychological effect extends well beyond actual filings, creating a "chilling effect" among naturalized Americans who fear their citizenship could be questioned based on minor application errors from decades ago [19].

For immigration law scholars, the question is not whether the government has the authority to denaturalize individuals who committed fraud — it clearly does — but whether a quota-driven system designed to produce thousands of referrals annually can be reconciled with the individualized, evidence-intensive process the courts require.

The answer, so far, appears to be no. But the administration has shown no signs of abandoning the effort, and with 2,600 potential cases already in the pipeline, the litigation is likely to intensify through 2026 and beyond [10].
