So you don't speak the native language of the country you might go back to? I'm certain there are emigrees who came to the UK very young whose parents wanted them to assimilate, but somehow I doubt that's the majority. There will also be people, especially Eastern Europeans, who will want to move to a different EU country than their origin, but again this is the same kind of move they made to the UK to begin with, unless English language education has gotten much better since I lived there.

I'm not sure I get your point or what are you trying to explain / show / support.
