They may tell you that they will upgrade you but never will. There was even a case where one fellow was hired as a Captain and unfortunately came over based on a verbal agreement got to Kuwait and they told him never mind we raised our mins. (now they say 5000 jet) and you only qualify as a F/O. Case in point; never I say never make a move without a signed contract. Also make sure in the contract that they will provide you with you Civil ID before you start flying. One cannot do anything hear without your residency permit. Long story this is how they will attempt to keep you on a short leash. There are to many pitfalls to speak of here. If you are serious look at it as a means to an end. A good introduction to the ME, spent you 6 to 8 month and pay off some bills then move on to better horizons. If you are typed do not sign a bond agreement. Keeping you current on type is a cost of their business not yours!
