DOJ Files Record 40 Denaturalization Suits Against Naturalized Citizens

Key points

• The Justice Department filed 40 denaturalization complaints between August 21 and October 2, 2026, marking the largest single-period effort in the current administration.
• Attorney General Todd Blanche stated the defendants concealed critical facts and represent serious criminal offenders, including espionage and sexual offenses against minors.
• At least 19 of the 40 individuals face proceedings primarily for lying on visa or naturalization forms, rather than for violent crimes.
• The individuals range in age from 26 to 76 and come from various countries, with Mexico having the highest representation (11 individuals).
• Critics and legal experts argue that denaturalization is historically rare and that the expansion of these cases risks statelessness and serves as a political tool.

Background

This move follows a broader trend under the Trump administration to ramp up denaturalization efforts. In June 2025, the DOJ issued a memo instructing its civil division to expand denaturalization categories. Previous batches included 17 cases in June 2026, 10 in July, and 25 in August. The administration has also faced legal challenges regarding birthright citizenship, with a Maryland federal judge blocking executive orders aimed at limiting citizenship for newborns in September 2026.

How outlets are covering it

The Justice Department and Attorney General Todd Blanche frame the denaturalization actions as a necessary measure to maintain national security and protect the integrity of US citizenship, emphasizing that the defendants 'lied their way' into citizenship. In contrast, critics and legal experts, including the Transactional Records Access Clearinghouse (TRAC), argue that denaturalization is historically rare and that the expansion of these cases risks statelessness. TRAC researchers noted that denaturalization is becoming increasingly common and that the DOJ is 'highly selective' about which cases it publicizes. Additionally, some individuals' attorneys, such as Simon Sandoval-Moshenberg for Walid Osman, argue that the DOJ's filings are riddled with errors and that their clients have no criminal record, vowing to fight the cases in court.

Why it matters

The denaturalization process is a powerful tool that can strip individuals of their US citizenship, potentially rendering them stateless. The record number of cases filed in a single period signals a significant shift in immigration enforcement and citizenship policy, raising concerns about the legal and human rights implications of such actions. The expansion of denaturalization efforts also reflects the broader political and legal battles over the definition and protection of US citizenship.

What to watch

The 40 denaturalization cases will proceed through the federal court system, where the government must prove that the individuals illegally procured their citizenship or concealed material facts. The outcomes of these cases could set precedents for future denaturalization efforts and influence the legal standards for stripping citizenship. Additionally, the administration has indicated plans to file at least 250 denaturalization cases by October 2026, suggesting that more cases may be announced in the near future.
