Licence conversion can be done at GACA UAE but there are some caveats that you might find difficult to meet.
- Your licence has to be accepted, not all are convertable so if you have one from some funny place that is either unknown to them or not in high regard then you might have to jump through some hoops.
- You will need a dispatcher job in the UAE and a letter from the company explaining that you work there. They don't just convert licences and let you off job hunting.
- At the very least you will probably have to undergo recurrent training at the local shool (Next class in Nov I think)
There is a rumour that the licence period of validity is about to be increased from 2yrs to 8yrs and that the fee for this is going to be big (still waiting to see what happens there, might just be all talk)
Hope that helped,
Good luck.
