US birthright citizenship for Eileen Gu, acquired at birth in San Francisco, receives strong constitutional protections that limit revocation to narrow circumstances such as proven fraud or specific statutory violations rarely applied outside denaturalization cases. Recent DOJ actions targeting dozens of naturalized citizens for concealment of crimes or espionage have focused exclusively on individuals who obtained citizenship through the naturalization process, not birth citizens, with no filings or investigations reported involving Gu despite her long-public choice to represent China in competition. Trader consensus at 98.5% probability of no revocation reflects this structural barrier and the absence of triggering developments. Late shifts could still arise from new criminal charges meeting revocation thresholds or unforeseen legislative changes, though both remain distant given current enforcement patterns.
