What I don't like about these stories is that they're always about the type of immigrant that British people are happy to have, i.e. white, educated people from English-speaking countries. Even when not actually stated, it always implies (and often is outright stated in the comments sections), 'Why do we let in all these impoverished muslim darkies so easily while forcing out useful English-speaking white people?' And as others have said, it often turns out that the 'useful' immigrant has actually just not bothered to do things the right way because they also thought, subconsciously or otherwise, that 'useful' immigrants shouldn't have it so hard and they should get their visa for being so great (and white, and English-speaking).
