since flight training is very low quality in iran, i need to go to another country to get my trainings and i want to get high quality training
CTC would offer high quality training, as would some other major multinational schools outside the USA. Check reputations outside their own country to find out - that is, does a UAE school have a good reputation around the rest of the Middle East? I believe some of them do.
Pilotchute, really? The OP wants quality and you are extolling the benefits of cheap? RTQ lad, RTQ.
