Carsickpuppy is right on the money, nothing happens in a hurry with DCA Malaysia
If you try to contact them directly it will even slow down the application further... I suggest you have your HR dept email you the Airlaw test 1 and 2 sample papers to practice, as do not think for a minute it will be a walk in the park..many have failed on their first attempts
If your job offer is done by an Offshore operator, could be as stated 3 months or so; if not an offshore operator, anything up to 12 months
Your position has to be advertised locally first; if no Malaysian can fill it, then your work permit will be considered favorably and only then will DCA proceed with your license validation
