I understand, but sometimes you are not in a strong position to negotiate especially when you do not have a lot of experience. You know it's frustrating to miss an opportunity to work but well maybe this isn't an opportunity after all. But for sure I think you're right, if they don't agree to remove the clause I'll not accept.
My wish is to see the possibilities for career development and also in terms of wages. But above all to remove this clause. Regarding salary, what do you think? From how much it would be acceptable? QAR6500, 7000, 7500?
