The administration of President Donald Trump has expanded efforts to revoke citizenship from naturalized Americans, intensifying a legal strategy that federal officials say is aimed at addressing fraud in the immigration system.
According to statements from the United States Department of Justice, the government is currently pursuing denaturalization cases against 12 individuals from countries including Kenya, India, China, Nigeria, Somalia, Morocco, Colombia and others.
Officials say the cases involve allegations ranging from immigration fraud and identity deception to links with terrorism, war crimes and other serious offenses.
Acting Attorney General Todd Blanche said the administration is “taking action to correct egregious violations of our immigration system,” adding that the Justice Department has increased staffing to identify additional cases.
Expanded enforcement under Trump
The move reflects a broader shift in immigration enforcement under President Trump’s current term, which has emphasized both illegal and legal immigration scrutiny.
Officials say denaturalization has become a priority area within the Civil Division of the Justice Department, which now reviews past naturalization approvals for potential fraud or misrepresentation.
Assistant Attorney General Brett A. Shumate said the department is “filing denaturalization actions at record speed to restore integrity in the naturalization process.”
The current wave of enforcement includes individuals accused of serious crimes as well as those alleged to have used false identities during their immigration applications. Among the cases is a former diplomat accused of spying for Cuba, as well as individuals accused of having ties to extremist organizations or involvement in war crimes.

A separate case involves Manuel Rocha, a former U.S. diplomat who reportedly admitted to acting as a Cuban intelligence asset for decades while holding American citizenship.
Sharp increase in denaturalization cases
Data from the Justice Department indicates a sharp rise in denaturalization activity compared with historical levels. Officials say 15 individuals have already had their citizenship revoked since January 2025, out of 22 total cases filed during the same period.
This marks a significant increase from previous decades. Between 1990 and 2017, federal prosecutors filed just over 300 denaturalization cases, averaging roughly 11 cases per year, according to government records.
The use of denaturalization has historically been rare due to the high legal burden required. The government must prove either that citizenship was obtained through fraud or that the individual was never legally eligible to become a citizen in the first place.
Legal framework and Supreme Court limits
Denaturalization applies only to naturalized citizens and cannot be used against individuals born in the United States. Cases must be heard in federal court and require a high standard of proof.

The Supreme Court of the United States has repeatedly ruled that citizenship can only be revoked in cases involving clear fraud or misrepresentation during the naturalization process.
The court has also emphasized that citizenship is a protected legal status that cannot be stripped for political reasons or general misconduct.
Why this matters
The expansion of denaturalization marks a significant shift in how the U.S. treats naturalized citizens, raising concerns about due process and legal protections. While the administration argues it is correcting fraud and strengthening immigration integrity, critics warn that broader enforcement could create uncertainty for millions of immigrants who became citizens through legal channels.
