If you dont have a B2 Licence with types then I suggest you give the Gulf a miss for now. As an unlicenced mechanic you will be on very low pay - most of the unlicenced guys are from the Subcontinent and as such the airlines get away with paying peanuts.
Advice is to get your licence and some suitable type ratings (A320 & A330 are both popular) and then give the gulf a try - even then you will not be paid any more than you would in Europe.
