Zohran Mamdani, New York City mayor since January 2026, became a naturalized U.S. citizen in 2018 after moving from Uganda as a child. Republican lawmakers have called for denaturalization proceedings citing his political statements and associations, yet immigration experts emphasize that revocation requires federal court proof of willful material misrepresentation or concealment during the application process, with no credible evidence presented to date. Denaturalization remains an exceptional remedy limited to narrow statutory grounds such as terrorism ties or fraud, applied sparingly in recent decades. Trader consensus at 99.7 percent against revocation before 2027 reflects these structural legal barriers and the absence of qualifying developments. Remote scenarios that could alter outcomes include newly surfaced documentation of application fraud or a successful DOJ civil action, both of which would still face lengthy judicial review.
