background, base experience & qualifications
read it as:
1.Whom you know
2.Passport
3.Who knows you....
I have no idea to discourage you but having in mind yoiur location( IRAN) I will be very suprised if you ever get decent job in ATC world. Most if not all is either security sensitive posts, or under direct control of British and American interests ( NATO) ,or simply they could afford ATCOs from highest rated units.Regardless your qualification,knowledge,personal quality ,wish to work somewhere your really chances are close to zero.
But who knows,never say never
