The first thing which a potential expatriate planning to work in Saudi Arabia should do upon receipt of his work visa is to get the job title verified from someone who knows Arabic. You may be recruited as a doctor, engineer or a nurse but have probably been given a painter visa. No kidding, this has happened to many and people who have simply come on such visas have faced the herculean and near-impossible task of changing their job titles after landing in the kingdom. So what's all this fuss about job title in the visa?
Well, to begin with, you cannot bring your family into the kingdom. You may be a well-paid doctor or an engineer, but if your visa says that your profession is, for example, a laborer, then you cannot bring your family because laborers cannot afford / are not allowed to keep their families with them. Never mind if you are not one, but that's what your visa says! Strange, isn't it, but that's how it works here. You will also not be allowed to take a car driving license for certain lower level categories.
I had already mentioned in one of my earlier posts about this problem. The safest thing for you to do as soon as your visa has been stamped in your passport, is to go to someone who knows Arabic and get your job title mentioned in your visa translated and explained. This would save you a lot of trouble later when you come into the kingdom. Many employers simply bring people on whatever visa is available with them. Some of them may not even tell you about your job title on the visa, and those who do tell you may probably promise you that once inside the kingdom it can always be changed. Don't fall for it, because this is just next to impossible.
