First of all you will not be allowed to board the flight from Qatar if you dont have a pre arranged visa or your profession is falling under the agreed categories. I have seen a reply from aayinafathima who visited Dubai in July 2008. Now you are in 2010 and rules and regulations have been changed. I have two colleagues who are in Managerial Post but their profession in their ID was not Manager and they were held in Dubai Airport twice and warned. They asked the Company then to change their profession to Manager to enable them to travel to Dubai without any problem.
