Do you have all the requirements met? I mean at least 2500hr modern jet hours, ATPL and so on? I think they want every criteria met before they invite you to Dubai. I'm still lack of the ATPL until march, my collegue is lacking the hours which he's going to get by spring as well. Both of us are waiting for the invitation but they won't send it until all is clear for entry requirements.
Thanks for the response. Yes I already meet all the requirements.
