On June 11, 2025, the U.S. Department of Justice issued a sweeping enforcement memorandum that signals a renewed emphasis on denaturalization proceedings. Issued by Brett A. Shumate, Assistant Attorney General for the Civil Division, this memo outlines how the DOJ’s Civil Division will align its litigation strategy with directives from President Trump and Attorney General Pam Bondi.
Among the most significant shifts is the aggressive pursuit of civil denaturalization cases. This blog post dissects the key elements of the memo, particularly what naturalized citizens and immigration practitioners should know about the new denaturalization priorities.
Overview of the Civil Division Enforcement Memo
The memo lays out enforcement priorities across a range of legal and social issues, including civil rights, antisemitism, gender-related care for minors, sanctuary jurisdictions, and immigration fraud. All initiatives are framed as fulfilling the administration’s policy to restore federal authority, promote civil order, and ensure integrity in federal programs.
Civil denaturalization is now among the DOJ’s top enforcement targets—positioned alongside matters such as terrorism, war crimes, gang activity, and systemic fraud.
Legal authority for denaturalization
Under 8 U.S.C. § 1451(a), the U.S. government may initiate proceedings to revoke a person’s naturalization if it was:
- Illegally procured, or
- Obtained through concealment of a material fact or willful misrepresentation.
The memo emphasizes that revoking unlawfully obtained citizenship serves not just as a national security tool, but also as a safeguard for the integrity of the naturalization process.
Why denaturalization is being prioritized
The DOJ outlines several policy-based justifications for elevating denaturalization efforts:
- Preventing individuals linked to terrorism, espionage, or the illegal export of sensitive U.S. technology from holding U.S. passports
- Removing naturalized criminals, gang affiliates, or fraudsters who failed to disclose serious conduct during the immigration process
- Protecting federal benefit programs like Medicaid and Medicare from fraudulent claims tied to individuals who concealed eligibility issues
- Reinforcing public trust in the lawful path to citizenship by revoking benefits gained through fraud or deceit
The ten priority categories for denaturalization
The memo sets forth ten specific categories of individuals whose cases will be prioritized for denaturalization:
- Individuals who pose a national security threat, including those with ties to terrorism, espionage, or unauthorized exports of sensitive U.S. technology
- Individuals involved in war crimes, torture, or other human rights abuses
- Individuals affiliated with or supporting criminal gangs, transnational criminal organizations, or drug cartels
- Individuals who committed felonies that were not disclosed during the naturalization process
- Individuals convicted of human trafficking, sex offenses, or violent crimes
- Individuals who committed financial fraud against the U.S., including COVID-19 relief fraud (e.g., PPP loan abuse), Medicare, or Medicaid fraud
- Individuals who engaged in fraud targeting private entities, individuals, or companies
- Individuals who acquired citizenship through bribery, corruption, or other fraudulent means not already captured in other categories
- Individuals referred by U.S. Attorneys’ Offices due to pending criminal charges, even if those charges don’t fall under any other priority
- Any other case deemed sufficiently important by the Civil Division, even if it does not fall into one of the above categories
While the list serves as guidance, it is not exhaustive or ranked by importance. The Civil Division retains discretion to pursue other civil denaturalization actions as appropriate.
What about law-abiding naturalized citizens?
For the vast majority of naturalized U.S. citizens who have never been arrested, charged with a crime, or accused of fraud, there is no immediate cause for concern under this memo.
Civil denaturalization cases are almost always triggered by some kind of law enforcement encounter, criminal prosecution, or federal agency referral. In nearly every instance, the Department of Justice must uncover evidence of misconduct—usually dating back to the naturalization process itself—such as fraudulent entries on the application, failure to disclose criminal activity, or obtaining a green card through misrepresentation.
For example, if someone is arrested years after naturalization and it comes to light that they had prior convictions or immigration fraud they never disclosed, that case may be reviewed. Similarly, if a person is discovered to have gained citizenship through false asylum claims or sham marriages, that might trigger a denaturalization inquiry.
But naturalized citizens who have complied with the law, paid taxes, and were truthful in their applications are not the focus of this memo. There is no indication of any plan to revisit citizenship files at random or en masse. In fact, the entire memo focuses on serious categories of misconduct like national security, violent crime, and systemic fraud.
Nonetheless, those who have concerns about omissions in their immigration history, or who relied on poor legal advice when applying for naturalization, may benefit from a legal review of their file. Proactive counsel can help identify whether any aspect of their citizenship might be vulnerable if future issues arise.
Can the government open someone’s immigration file simply because they are disliked or controversial?
The memo’s aggressive stance on denaturalization has raised broader questions about whether immigration files of high-profile individuals—such as business leaders or political critics—can be reviewed based on political motives or personal animosity. Although former President Trump recently remarked that Elon Musk’s naturalization should be “looked into,” it is unclear whether that statement reflected a genuine policy directive or a rhetorical flourish. Still, it underscores a real question: can the government pull someone’s file simply because they don’t like them?
Technically, there is no law that prevents the Department of Homeland Security from reviewing an individual’s immigration or naturalization file if requested by senior officials, including the White House or Department of Justice. Officers at U.S. Citizenship and Immigration Services have the authority to access A-files and naturalization records for law enforcement or fraud investigation purposes.
There are privacy laws, such as the Privacy Act of 1974 and internal confidentiality rules, that govern how personal information is handled. However, these laws do not prohibit internal government use of immigration records when related to law enforcement or investigative purposes—even if the review is initiated for discretionary or policy-based reasons.
In practical terms, if DOJ officials request DHS to review a specific person’s file, the agency can conduct that review. If any discrepancies or red flags are discovered—such as misrepresentations in Forms N-400 or I-485—that information may be referred back to DOJ for further investigation, including possible denaturalization.
That said, immigration agencies and DOJ attorneys are still bound by evidentiary standards, legal thresholds, and constitutional protections. Even if a file is pulled for review, denaturalization can only occur through a federal civil lawsuit, where the government must prove unlawful procurement of citizenship by clear, convincing, and unequivocal evidence. Courts will not allow political motivations alone to justify denaturalization if the evidence is lacking.
In short, while the government can review an immigration file, it must still follow legal standards before it can revoke citizenship. The concern is not so much that files may be opened, but whether enforcement decisions are being made fairly and based on facts—not politics.
Enforcement scope and discretion
To maximize impact, the DOJ has authorized flexible assignment of denaturalization cases across teams within the Civil Division based on experience and subject-matter knowledge. This decentralized approach is designed to ensure timely prosecution of cases with national implications.
Importantly, the memo clarifies that while these ten categories help prioritize limited resources, they do not constrain the department from pursuing other civil denaturalization actions supported by evidence.
A broader civil enforcement strategy
The June 2025 memo is not limited to immigration and naturalization. It also advances initiatives that include:
- Prosecuting civil rights violations related to discrimination, particularly in entities receiving federal funds
- Combatting antisemitism through civil litigation and task force coordination
- Investigating fraud and misbranding related to gender-affirming medical treatments for minors
- Challenging sanctuary city policies and other state or local measures perceived to obstruct federal immigration enforcement
Conclusion
This Civil Division memorandum represents a profound shift in how the Department of Justice will use its authority in the years ahead. While denaturalization remains legally complex and politically sensitive, the memo makes clear that the DOJ under the Trump administration is willing to push forward aggressively in this space.
Naturalized citizens should ensure they maintain accurate immigration records, and those with legal questions or concerns about past disclosures during the naturalization process are encouraged to consult qualified immigration counsel.
