Justice Department Files 40 Denaturalization Cases in Unprecedented Push to Strip Citizenship

The United States Department of Justice announced on Monday that it has filed 40 new lawsuits seeking to revoke the citizenship of naturalized Americans, marking what federal prosecutors describe as the largest denaturalization effort in modern American history. The petitions, submitted between late August and early October, target individuals accused of serious offenses including money laundering, child sexual abuse, visa fraud, and tax evasion.

According to a statement released by federal prosecutors, the 40 individuals named in the complaints come from a diverse array of countries, including Mexico, Pakistan, China, and Sierra Leone. Authorities allege that these individuals concealed criminal acts and other material facts during their citizenship application processes, effectively obtaining naturalization under false pretenses. The Justice Department maintains that their criminal convictions, which largely occurred after they took their oaths of citizenship, should have prevented them from becoming Americans in the first place.

Attorney General Todd Blanche characterized the filing as a landmark moment in the administration's immigration enforcement strategy. "Today's announcement marks the largest denaturalization effort in modern history," Blanche said in a statement. "Under President Trump's leadership, the Department of Justice will continue to employ the denaturalization process to maintain our national security and protect the American people." The statement emphasized that the cases represent the highest volume of denaturalization petitions submitted in such a compressed timeframe under the current administration.

Among the most serious allegations are claims that two individuals on the list engaged in espionage on behalf of China. Prosecutors argue that committing such crimes before obtaining citizenship demonstrated a lack of "good moral character," a legal standard required for naturalization. Under US law, prosecutors can petition courts to strip citizenship from foreign-born individuals if they willfully concealed a material fact during their application that would have otherwise disqualified them from approval.

The legal mechanism for denaturalization has existed for decades but has historically been reserved for exceptional circumstances. Following World War II, the US government initiated proceedings against dozens of citizens accused of concealing involvement in the Holocaust or participating in war crimes. One notable historical case involved Emma Goldman, a Lithuanian-born anarchist and women's rights activist who was jailed in 1917 for antiwar activities before being denaturalized and deported to the Soviet Union. However, the practice became increasingly rare after the Cold War ended, with denaturalization prosecutions falling to just a handful of cases per year.

The Trump administration has sought to dramatically expand the use of denaturalization as part of a broader strategy to conduct the largest deportation operation in American history. Top officials have argued that denaturalization serves as a critical tool for removing individuals who fraudulently obtained citizenship and subsequently committed crimes on American soil. The Justice Department has framed the effort as a matter of national security and public safety, asserting that those who conceal criminal histories or engage in espionage should not be permitted to retain the privileges of citizenship.

Human rights organizations and civil liberties advocates have pushed back against the expansion, warning that the proceedings could leave individuals stateless and vulnerable. Critics argue that denaturalization cases often rely on technicalities in citizenship applications that may have been unintentional errors rather than deliberate fraud. They also contend that the administration has selectively targeted specific groups perceived as political rivals or enemies, raising concerns about the politicization of the denaturalization process.

The administration's broader immigration enforcement agenda has included indications that it would seek to denaturalize large numbers of Somali Americans following allegations of daycare fraud involving the Somali diaspora in Minnesota. President Trump wrote at the time, "Send them back from where they came, Somalia, perhaps the worst, and most corrupt, country on earth." The statement drew widespread condemnation from immigrant rights groups who viewed it as targeting a specific community based on national origin.

Members of Trump's Republican Party have also floated the possibility of revoking citizenship from New York City Mayor Zohran Mamdani, who was born in Uganda. Representative Andy Ogles and others have suggested Mamdani's citizenship could be challenged, while Trump himself has falsely claimed the mayor may be in the country illegally. At one point, Trump even raised the idea of withdrawing citizenship from tech entrepreneur Elon Musk, a close ally and adviser during his second administration, after the two men had a falling out in 2025.

The administration has also pursued efforts to dismantle birthright citizenship, which is granted to virtually all children born in the United States, with limited exceptions for the babies of diplomats and foreign military forces. Birthright citizenship is protected under the US Constitution and cannot be revoked in the same manner as naturalized citizenship. In June, the Supreme Court struck down Trump's initial efforts to dismantle birthright citizenship, but legal battles have continued after the president issued a second executive order seeking to restrict how birthright citizenship is applied.

Legal experts note that denaturalization cases require the government to prove that an individual willfully concealed a material fact during the naturalization process. This is a high legal standard, and courts have historically been reluctant to strip citizenship except in cases involving severe fraud or serious criminal conduct. The outcomes of the 40 newly filed cases will be closely watched as indicators of how aggressively the administration can pursue its denaturalization agenda through the courts.
