Is it true that children whose parents r in QP or its subsideries has a certain advantage in applying for int'l schools?

My wife n I are very concern of the limited avails of schools for my daughter. We actually have intention to enrol her in DESS but understand there is a long waiting list. What should we do if there is no such priority ? Any advise ?

I understand RGas will only pay for the equivalent of the int'l school of the employee's orgin. What if there aren't any of it in Qatar? Will RGas then pay for thye full fees?
