Zohran Mamdani, a naturalized U.S. citizen since 2018 after arriving from Uganda as a child, faces no substantiated legal basis for denaturalization under current statutes, which require proof of fraud or specific disqualifying conduct during the application process. Republican lawmakers and former President Trump raised questions during the 2025 New York City mayoral campaign, prompting calls for investigations into his paperwork and eligibility, yet federal agencies have taken no formal steps and fact-checking has identified no supporting evidence. The Department of Justice denaturalization process involves lengthy litigation and court review, creating structural barriers to completion before 2027. Trader consensus reflects these procedural realities alongside the absence of active proceedings, though a newly discovered material misrepresentation or statutory change could theoretically reopen the question.
