The Trump administration on Monday plans to announce it is seeking to revoke the citizenship of 17 U.S. citizens accused of immigration fraud, expanding its unprecedented denaturalization campaign, CBS News has exclusively learned. 

Justice Department officials said the move represents the largest-ever effort by the U.S. government to use its denaturalization powers, which were rarely invoked before President Trump returned to the White House last year with promises to launch a historic deportation blitz. Between 1990 and 2017, the Justice Department filed an average of just 11 legal complaints per year seeking to denaturalize American citizens, historical figures indicate.

Federal law has long allowed the government to try to denaturalize foreign-born U.S. citizens who officials believe committed fraud to obtain their citizenship, such as by concealing information, like criminal conduct, on their immigration applications. But the process has been historically lengthy, complex and seldom exercised, requiring officials to persuade judges to strip naturalized citizens of their citizenship in civil or criminal proceedings in federal court. 

The Trump administration has sought to vastly escalate denaturalization efforts as part of its larger crackdown on illegal and legal immigration. In 2025, the Justice Department broadened the categories of naturalized citizens who should be prioritized for denaturalization. Last month, officials announced a dozen denaturalization cases, at the time the largest such effort in years.

Some of the 17 citizens targeted in the latest denaturalization campaign were convicted of violent or serious crimes, including sex offenses against children. Others were convicted of fraud crimes or accused of committing immigration fraud. 

In federal court complaints filed across the country in recent days, Justice Department officials argued that the individuals concealed their criminal activity when they applied for U.S. citizenship or were otherwise ineligible to be naturalized, including because they lacked a "good moral character," one of the requirements in the naturalization process.

Those targeted in the latest round of denaturalization cases include a Haitian immigrant who allegedly sexually abused his daughter; a man from the former Yugoslavia convicted of sexually abusing a child under the age of 15; an immigrant from Mexico convicted of receiving sexually explicit images of minors; a former Catholic priest born in Colombia accused of child sex abuse; and a Filipino-born man who pleaded guilty to a child sex crime.

The group also includes an Indian immigrant accused of filing fraudulent H-1B visa petitions; the daughter of a Colombian drug trafficker accused of money laundering; a man born in Jamaica convicted of wire fraud; and a Cuban-born woman accused of defrauding a tribal casino. Other naturalized citizens were accused of using false identities.

Acting Attorney General Todd Blanche said the Justice Department would have "zero tolerance" for abuse of the naturalization process.

"Criminal aliens are lying about their past crimes, including drug dealers, sexual predators, and fraudsters," Blanche said. 

Homeland Security Secretary Markwayne Mullin said the Trump administration would "continue to use every lawful avenue to denaturalize and remove aliens."   

"American citizenship is a privilege, and it must be earned honestly. If you come here, break our laws, and lie in your immigration proceedings, you forfeit that privilege," Mullin said.

The denaturalization process allows the targeted citizens to challenge the government's filings to try to retain their citizenship. If U.S. citizens are denaturalized, they return to their prior immigration status, typically as permanent U.S. residents, and lose all the legal benefits of American citizenship, including protection from deportation.
