On May 8, 2026, USCIS and the Department of Justice announced coordinated denaturalization actions against 12 naturalized U.S. citizens, filing civil complaints in federal district courts across the country. The cases involve allegations of concealing terrorist support, war crimes, espionage, and sexual abuse of a minor at the time of naturalization.
The announcement is part of the Trump administration’s broader push to use denaturalization as a law-enforcement tool — an authority that has historically been used sparingly but is being exercised with new frequency in 2026.
What Is Denaturalization?
Denaturalization (also called “denaturalization” or revocation of naturalization) is a legal process by which the U.S. government revokes a person’s citizenship and cancels their Certificate of Naturalization. Under Section 340 of the Immigration and Nationality Act (INA), a naturalized citizen’s citizenship can be revoked if:
- The naturalization was illegally procured (obtained in violation of law), OR
- The naturalization was procured by concealment of a material fact or by willful misrepresentation
In the cases announced May 8, DOJ alleges that each of the 12 individuals lied on their naturalization applications — specifically by concealing criminal conduct, terrorist ties, or other disqualifying information that would have rendered them ineligible for citizenship.
Notable Cases Among the 12
Ali Yousif Ahmed Al-Nouri (Iraq, age 48)
Iraq requested Al-Nouri’s extradition in 2019 to face criminal charges for the premeditated murder of two Iraqi police officers in 2006, allegedly committed in his capacity as a leader of Al-Qaeda in Iraq. DOJ alleges he concealed this conduct when he naturalized in the United States.
Oscar Alberto Pelaez (Colombia, age 75)
A Colombian Roman Catholic priest who pleaded guilty to 13 counts of sexual assault against a child in 2002. He naturalized in 2006, and just one year later began sending tens of thousands of dollars to Al-Qaeda using fraudulently obtained funds. DOJ alleges he was not truthful about his principles or associations during naturalization.
Salah Osman Ahmed (Somalia, age 43)
Ahmed naturalized in 2007, and DOJ alleges he was not genuinely attached to the principles of the U.S. Constitution at the time of naturalization. Within months of receiving citizenship, he allegedly began providing material support to a designated foreign terrorist organization.
How Denaturalization Proceedings Work
Denaturalization is a civil proceeding, not a criminal one — though the underlying conduct may also be the subject of criminal prosecution. The process works as follows:
- Step 1: DOJ Civil Division or a U.S. Attorney’s Office files a civil complaint in federal district court
- Step 2: The defendant is served and has the right to respond, retain counsel, and contest the allegations
- Step 3: If the court finds by clear and convincing evidence (a high standard) that citizenship was illegally or fraudulently obtained, it orders denaturalization
- Step 4: The individual’s Certificate of Naturalization is canceled and returned to USCIS
- Step 5: The person reverts to whatever immigration status they held before naturalizing (e.g., lawful permanent resident) — or, if they had no underlying status, becomes deportable
Critically, U.S.-born citizens cannot be denaturalized — the Fourteenth Amendment protects birthright citizenship from revocation in virtually all circumstances. Denaturalization only applies to those who became citizens through the naturalization process.
DOJ denaturalization cases May 2026 — the 12 cases, grounds alleged, and how the process works.
Broader Context: Rising Denaturalization Enforcement in 2026
Before the Trump administration, denaturalization proceedings were rare — typically fewer than a dozen cases per year, usually involving Nazi war criminals, sex offenders, or national security threats. In 2026, USCIS Director Joseph Edlow has publicly stated that the agency is re-checking older green card and citizenship approvals where fraud is suspected, and that USCIS is expanding fraud detection efforts with ICE and CBP .
Naturalized citizens should be aware that:
- There is no statute of limitations on denaturalization proceedings under current law
- A single material misrepresentation on a naturalization application — even decades ago — can provide legal grounds for denaturalization
- The government does not need to prove you committed a crime; it only needs to prove you concealed material information that would have disqualified you
For the vast majority of naturalized citizens who answered their naturalization applications honestly, these proceedings present no risk. The cases announced in May 2026 involve alleged concealment of terrorism, war crimes, and violent crime — not typical immigration or visa violations.
