Anyone representing a country, should be allowed to reside in that country even after he/ she quits playing the sport.

Correct me if I'm wrong, but from what I have heard, in Qatar, players are given passports only to represent the country for the duration they play the sport and are only allowed to use the passport for travel related to a sporting event while representing the country.

If traveling on vacation, they have to use their own passport. The passports were taken back after the sporting event.
