Good questions. Somehow a guide for him before coming up here. A lot of people misunderstood the Contract and did not bother to ask. It is very tempting to accept and calculate the equivalent of the money that they will be receiving here, little did they know it is misleading the employee and it is too late to realize that each statement stipulated in the contract  is not limited to. The questions asked by Marie must be taken seriously and must be asked prior to your flight here in Doha. Make everything clear and be wiser. Good luck!
