Khalifa used to send most of their kids to the UK but I heard that Immigration have stopped issuing visas to them. Hardly surprising with all the Algerian terrorist suspects that have been popping up in the news. I have not seen any non-Algerian cadets but I heard that there were a few French guys flying the ATR 42 so they do take foreigners. Whether they do at cadet level I don't know.
Why don't you phone or e-mail their Director of Flight Ops. I am sure he will have the answers to your questions or at least find someone who can.
