Re: foreign forum....
^^ I agree that quite a lot of Pakistanis living in the US don't even dream about moving back to Pakistan.
But there are a lot of exceptions and I don't think you should generalize your statement like that. I have quite a few of those "exceptions" in my family, ie relatives who either have moved back to Pakistan after living in the US for some years or are planning to do so soon.
And also the very fact that a lot of "American Pakistanis" are active members of this forum shows how much they relate themselves to Pakistan. Otherwise they wouldn't join a Pakistani forum, would they?
