Abstract: More and more athletes change their sports nationalities in order to participate in major international games such as the Olympic Games. One precondition for an athlete to participate in an international game is that the athlete should meet game qualifications specified by relevant international sport organizations, for example, a party concerned who applies for sports nationality changing must be actually related to the citizenship applied country in terms of birthplace, ancestor birthplace and residence time, although the nationality laws of some countries do not require similar stipulations. A country can grant citizenship to a foreign athlete in an express way so that the athlete can represent the country to participate in a game. As for a dispute about nationality changing, if a party concerned refuses to accept the decision of the international sports organization, the party concerned can appeal to the Court of Arbitration for Sport, which is a good institution for resolving disputes. Protecting the interests of related athletes is a factor that should be considered first.
