You should probably specify it is where they were actually born. For example Komarov is Finnish, he played for Finland at the Olympics. Khudobin has always played for Russian national teams. Regehr & Adams are both Canadian citizens, and probably never even played hockey in either of their birth countries. It would be nice if you specified that it was birth countries.

Alexander Georgiev is from Bulgaria
Yutaka Fukufuji is from Japan
