Trump Pledges Expanded Effort to Revoke Citizenship in Fraud-Based Naturalization Cases

President Donald Trump said Tuesday that his administration will move to revoke the citizenship of naturalized immigrants convicted of defrauding American citizens, signaling a potential expansion of federal denaturalization efforts.

Speaking at the Detroit Economic Club, Trump stated that his administration would pursue revocation of citizenship for “any naturalized immigrant from Somalia or anywhere else who is convicted of defrauding our citizens.”

The remarks came as the U.S. Department of Justice announced the creation of a new section dedicated to investigating, prosecuting, and pursuing denaturalization cases. The move builds on a denaturalization task force first established in 2018 during Trump’s initial term in office.

A Formalized Denaturalization Section

According to DOJ officials, the newly created office will prioritize cases in which individuals allegedly “illegally procured” U.S. citizenship or concealed “a material fact” during the naturalization process. The department said enforcement efforts would focus on serious violations of law, including terrorism, war crimes, sex offenses, and significant financial fraud.

Denaturalization — the legal process through which citizenship is revoked — is permitted under U.S. law when the government can demonstrate that citizenship was unlawfully obtained through fraud or material misrepresentation.

The Supreme Court has consistently held that citizenship may not be stripped unless it was illegally procured. The government must meet a high evidentiary threshold, providing “clear, unequivocal, and convincing evidence” in federal court.

Historical Context and Legal Limits

Historically, denaturalization has been rare. Following a 1967 Supreme Court ruling that limited the practice strictly to cases involving fraud or error in the naturalization process, the federal government typically filed only about a dozen denaturalization cases per year for several decades.

That pattern began to shift in the late 2000s.

In 2008, under the administration of President Barack Obama, federal officials launched “Operation Janus,” an initiative that used digitized fingerprint records to identify individuals who had been ordered deported under one identity but later obtained naturalized citizenship under another.

During Trump’s first term, the administration expanded those efforts substantially, reviewing more than 700,000 naturalization files and increasing the number of cases filed in federal court.

In 2017, the Justice Department filed 25 denaturalization cases. Another 20 cases were filed during the first half of 2018 — a notable increase compared with prior decades. In January 2018, DOJ officials said they anticipated pursuing roughly 1,600 denaturalization cases and sought to hire additional attorneys and immigration officers to support the initiative.
