I have cousins and brothers who have married back home - this is one of the top reasons, so they dont have to put up with the 'attitude' girls living abroad have. By attitude they mean a backbone. I've sat with aunties who have discussed this very topic, girls from back home are preffered cause they are 'seedi saadi' and 'mooh por kay javab nahin dehti'.
There is a difference between arrogance/attitude and backbone.
Girls from back home are not uneducated. There are plenty of educated girls in Pakistan. From what I know, a lot of guys tend to want somebody from back home because she has been raised in a different culture - and might have traits that they admire and want once they start their own family.
There is a major difference between people born/raised here, and there. There are certain qualities that people have there that you don't find here. Vice versa. But I guess if one is a Pakistani, and values certain cultural aspects in a woman , they are most likely to be found in somebody from back home. Some guys prefer somebody from there , and there is nothing wrong with it. It does not mean they want to control an uneducated woman.
