Eileen Gu, the U.S.-born freestyle skier who competes for China, holds birthright U.S. citizenship with no official record of formal renunciation or expatriation in Federal Register listings. China’s nationality law prohibits dual citizenship and required renunciation upon her 2019 naturalization, yet she maintains a Chinese passport and has faced public scrutiny and online criticism over her status during the 2026 Winter Olympics. U.S. law permits dual nationality, and involuntary revocation remains rare, typically limited to specific criminal convictions or voluntary acts rather than athletic representation or passport holdings. Recent petitions and commentary have called for clarification from the State Department without prompting formal proceedings. Trader consensus at 95.5% for no revocation aligns with the high legal and constitutional barriers to stripping birthright citizenship absent extraordinary developments.
