No, no, I guess you are still somewhat confused over the system that works here. As I have stated earlier the employer is simply helpless in getting the type of visa he has applied for. He may have applied for your category but was issued a "labourer visa" instead. I suggest you don't make this into an issue. Just grab the opportunity and come here when you will get to understand things better through your Kabayans. There are many here whose profession are different from the type of visa they have. It hardly matters especially when you don't need a driving license or plan to bring your family here, At the end of the day, it is the Riyal you have in your pocket that matters.
