Status: In litigation — DOJ civil denaturalization initiative (TRAC Report 774) (8 U.S.C. § 1451(a) (INA § 340); DOJ Civil Division enforcement-priorities memo (June 11, 2025); TRAC Report 774)

Next step: In June 2026, news outlets reported — citing a senior Justice Department official — that the DOJ aims to file at least 250 civil denaturalization cases in federal courts by the end of fiscal year 2026 (September 30, 2026). Watch for the fiscal-year filing total and for rulings in individual district-court cases, which are decided one at a time.

What’s happening

Who it affects

Naturalized U.S. citizens — people born abroad who later became citizens. Civil denaturalization under 8 U.S.C. § 1451(a) (INA § 340) asks a federal court to revoke citizenship the government says was “illegally procured” or obtained by concealing a material fact or by willful misrepresentation. The June 11, 2025 DOJ Civil Division priorities memo lists the categories the government says it will pursue first, such as national-security or terrorism ties, war crimes or human-rights violations, gang or cartel affiliation, serious undisclosed crimes, and government-program fraud. Unlike criminal denaturalization, the civil process has no jury, no government-appointed defense attorney, and no statute of limitations; the government must prove its case by “clear, convincing, and unequivocal” evidence. U.S. citizens by birth are not affected. This is general information, not legal advice.

How it got here

Jun 11, 2025 The DOJ Civil Division issues a memo, signed by Assistant Attorney General Brett Shumate, making civil denaturalization an enforcement priority and listing categories of cases to pursue first.
May 31, 2026 TRAC later counts at least 15 civil denaturalization complaints filed during May 2026 — already far above the historical average of about 0.6 per month.
Jun 12, 2026 By early June, 18 more complaints are filed, bringing the total since May 1 to 33; six of the May–June cases are based on alleged false identity or immigration fraud.
Jun 17, 2026 TRAC publishes Report 774, documenting the surge in denaturalization filings.
Jun 18, 2026 News outlets report, citing a senior Justice Department official, that the DOJ plans to file at least 250 civil denaturalization cases in federal courts by the end of fiscal year 2026 (September 30).

Where does it stand right now?

The Justice Department is filing civil denaturalization lawsuits — court cases that ask a federal judge to revoke the citizenship of someone who became a U.S. citizen through naturalization — at a sharply higher rate. The Transactional Records Access Clearinghouse (TRAC) counted at least 15 such complaints filed in May 2026 and 18 in early June 2026 (33 since May 1), compared with a historical average of about 0.6 per month. These are individual civil suits brought under 8 U.S.C. § 1451(a) in federal district courts across the country; each is decided on its own record and most remain pending. Denaturalization does not affect people who are U.S. citizens by birth. In June 2026, news outlets reported — citing a senior Justice Department official — that the DOJ aims to file at least 250 civil denaturalization cases in federal courts by the end of fiscal year 2026 (September 30, 2026). Watch for the fiscal-year filing total and for rulings in individual district-court cases, which are decided one at a time.
