How are Pakistanis treated in Saudi Arabia?
Foreign people can be categorized in to two groups there. Those coming from first world countries i.e. the West and those coming from third world countries like the subcontinent.
So the treatment is mostly similar to their nationalities. While its not the same in all cases, if you are from a third world country, you will be treated as a third class citizen and vice versa. The kafala system ensures you remain in your limits and if your sponsor (Kafeel) is a good person personally, you may find life easier. If he is an idiot, then may god have mercy on you, because your Kafeel or the government wont.
Usually If you are working for a company and not on a labour visa, you can still find somewhat justice, but if you are on a labour visa, then according a labour friend of my father, even god will forsake you.
Pakistanis are treated that way too. to them you are a Bakistani, in that case, you are at the mercy of your visa status and your sponsor. Since the Pakistani embassy in there is as useless as the Pakistani government in Pakistan, you are pretty much on your own.
I came back from Saudi Arabia in 2004, by then such was the case. if it has changed I wont be aware of it now but I often meet taxi drivers who came back from there and what they tell me sort of points towards the same experience I had seen there.
