Despite Eileen Gu's choice to compete for China, it's unclear whether she renounced her American citizenship -- usually a requirement for Chinese naturalization, since the country does not allow dual citizenship. Gu has never publicly commented on the status of her American citizenship, though an article on the official Olympic site referred to her "dual nationality" in January. At a news conference after her win on Tuesday, reporters asked Gu several times if she was still a US citizen.
