Its difficult to get a visa for Pakistani and so is for indians, however its not impossible either. Usually it depends largely on the repute of the sponsoring company.

But its not impossible too. Recently, I have seen many more of Pakistanis around. I think recent visits of prime minister and president would have improved the situation.

if Pakistan could focus and improve on diplomatic relations, Qatar could offer great opportunities for many qualified and dedicated professionals of pakistan.

By the way total population share of pakistanis in Qatar is only 4% :)
