Reasons for changing citizenship

Occasionally, an athlete will become a citizen of a different country to enable them to compete in the Olympics. This is often because they are attracted to sponsorship deals or training facilities in the other country, or the athlete might be unable to qualify from within their country of birth. In preparation for the 2014 Winter Olympics in Sochi, the Russian Olympic Committee naturalised a South Korean-born short-track speed-skater, Ahn Hyun-soo, and an American-born snowboarder, Vic Wild. The two athletes won five gold medals and one bronze medal between them at the 2014 Games.
