Why do a work visa in Qatar gets rejected???

I would be grateful for a reply. Why do a work visa in Qatar gets rejected??? Is it on the basis of an individual for whom the visa is applied or is it because of the sponsoring company?? How likely is that an individual gets the work visa if he/she reapply for another company after being rejected once before??

The visa granted to the companies without name of the employ, just the requirement will be granted and divided for many nationality not as per the company request for the candidate nationality, but as the labor committee decide to grant the list required with the number of candidate from each nationality, if the company to whom you apply have visa for Jordanian nationality, then the process of the visa will not take more than 3 days, but if the company have no visa for Jordanian nationality, then it will take very long time, the company apply apply again and again and meet with the labor committee and will have rejected result for many time, it is difficult to got visa for Jordanian and when it is for female it will be more difficult than visa for male.

Hello everyone,

Just to inform you that a new topic has been created with your post on the Qatar forum. ;) Thank you for your participation.

Is it true that most of the companies apply online?? In doing so, name of the person for whom the visa is applied can collide with the same name of the other person..does it affect the processing of a work  visa?
