Thanks Ehtesham Sahib,
Great to hear from you, if Pakistanis are being paid a lower salary whose fault do you think it is? Ours.
I worked as a hardware and communication engineer at IBM Saudi at their Al Khobar office, all the employees were being paid on the basis of their job title and skills rather than their nationality. Yes we had a system of hiring "ASSIGNIES" and "SECONDIES" from USA and Europe, these were highly skilled engineers who would get the salary in their home country as well as get the Saudi salary on top of it, but I believe this is a matter of supply and demand.
I see huge opportunities in "recycling industry" in Saudi Arabia, if you have any interest in this you may share it with me.
