In a sweeping move that could reshape the U.S. citizenship system, the Department of Justice announced Monday that it has filed denaturalization actions in federal district courts against 17 naturalized citizens.

The defendants, who hail from 13 countries—including Cuba, Haiti, Jamaica, the Dominican Republic, Trinidad and Tobago, Mexico, Colombia, former Yugoslavia, India, China, the Philippines, Somalia, and the Democratic Republic of the Congo—are alleged to have obtained citizenship through fraud, deceit, and serious criminal conduct. The charges range from child sexual exploitation and statutory rape to wire and securities fraud, insurance fraud, drug trafficking, and theft from a tribal casino.

"We maintain a zero‑tolerance policy for abuse of the citizenship privilege," Acting Attorney General Todd Blanche said in a DOJ press release. DHS Secretary Markwayne Mullin echoed that stance, stressing that citizenship must be earned honestly and that those who lie during immigration proceedings will forfeit the benefits they fraudulently acquired.

Of the 17 defendants, six—about 35 percent—are accused of concealing serious child‑sex offenses. One case involves a Roman Catholic priest who allegedly groomed a child while using a clean immigration record to evade scrutiny. Other allegations include possession of illegal images of minors. Financial crimes also feature prominently: a $54 million securities and wire‑fraud scheme, a $36.7 million billing fraud that siphoned money from Blue Cross Blue Shield through nonexistent physical‑therapy clinics, and the use of funds tied to a Colombian drug cartel to purchase luxury real estate in the United States.

The DOJ’s filing also highlights elaborate identity‑fabrication schemes designed to bypass U.S. immigration vetting. Four defendants allegedly used fabricated names, misrepresented marital status to obtain green cards, and submitted multiple applications under different personas after initial denials. One woman, who had lived in the U.S. under a false name for nearly 30 years, was exposed when digitized fingerprint records linked her current identity to a 1995 denial.

These cases are part of a broader DOJ strategy aimed at restoring the integrity of the naturalization process. The agency’s December guidance directed U.S. Citizenship and Immigration Services to present 100 to 200 denaturalization cases per month in fiscal 2026— a sharp increase from the average of 11 cases per year from 1990 to 2017. This filing marks the first time the DOJ has pursued 17 cases simultaneously.

The denaturalization proceedings are now pending in federal courts. If a court finds that a defendant was ineligible for citizenship at the time of naturalization, the individual will lose U.S. citizenship and may become subject to deportation. No deportation orders have been issued yet, and the cases will proceed through the judicial process.

The DOJ’s actions signal a shift toward a more aggressive enforcement posture under the current administration. The agency says it will continue to pursue denaturalization cases that involve fraud or serious criminal conduct, with the goal of preserving the rights of honest, law‑abiding immigrants who have undergone the naturalization process.

The outcome of these cases will likely influence future policy and enforcement priorities. The DOJ has indicated that it will maintain its focus on denaturalization as part of a broader effort to protect the integrity of the U.S. citizenship system.
