Ach ach Özcan,
I hope with all other turkish pilots like us, that oneday this rule will be changed.
Well the turkish diploma or degree MUST be issued by the Turks. So if you have a diploma from a foreign university out of Turkey, you must go to the YÖK and take your "DENKLIK BELGESI". With this very very very important thing you will have your diploma issued by the Turks, but studied elsewhere. And please be careful on which University you go. Not every university in Turkey excepts the university where you are. That's it.
