The Trump administration escalated its immigration crackdown by seeking to revoke U.S. citizenship from 17 immigrants, marking a significant shift toward targeting legal immigrants. Justice Department filed denaturalization cases across federal courts for those accused of concealing crimes or committing fraud during naturalization, expanding beyond previous focus on undocumented immigrants.

Last month, officials sought to strip citizenship from 12 immigrants, with DHS now referring 200+ denaturalization cases monthly. The cases involve serious crimes including healthcare fraud, sexual battery, and visa fraud. Secretary Mullin stated citizenship "must be earned honestly," signaling a more aggressive enforcement posture.

This strategic pivot targets the legal immigration system itself, potentially disrupting businesses reliant on immigrant workers and creating uncertainty for naturalized citizens. Only about 130 denaturalization cases were filed between 2017 and July 2025, making the administration's recent actions a substantial escalation in enforcement priorities.
