Meb Keflezighi and Abdi Abdiraham became U.S citizens because they wanted to represent the U.S. The two athletes were good enough to make their respective teams in their former country. Sam Chelanga wants to become a U.S citizen he stated because he has more of a connection here than in Kenyan.
Sally Kipyego loves running so much that before 2010 she applied for U.S citizenship because she felt it was her best chance to make World and Olympic teams. In 2010 she advanced to another level and gain huge confidence; therefore, her desire to see if she can make the Kenyan team this year. I love Sally but feel is she fails to make the Kenyan team her process for gaining U.S citizenship should start ALL OVER!
Stick with one country you want to represent Sally!
