Overview
- The Justice Department filed civil denaturalisation complaints against 40 people, a set of cases the agency announced on Monday, Oct. 5, 2026, and described as the largest single-period filing under the current administration.
- The complaints allege a range of misconduct that the DOJ says was concealed during naturalisation, including serious criminal conduct, identity fraud, fraudulent marriages and immigration-related lies.
- The filings name specific defendants such as Lazaro Eduardo Trujillo Viton and Andrew Coldicutt as examples, but the claims are allegations that the government must prove in federal court before any citizenship can be revoked.
- This action follows earlier DOJ batches in July and August and tracks with an August 2025 USCIS directive that raised standards for naturalisation, a change linked in reporting to sharp drops in approval rates and broader DHS enforcement figures.
- If courts rule for the government, affected people could lose citizenship and face removal or other penalties, and the campaign could further chill naturalisation applications and add pressure to labor and immigration outcomes already cited by analysts.
