I often think about this but regardless of the country, some foreign nationals can never imagine going back to their home country and others always see their home country as their home, where they will end up. It seems more specific to the foreign national than to the home country.

Some people immigrate for purely economic reasons, others immigrate because they prefer the lifestyle and culture in the host country. The ones that always see their home country as their home, where they will end up, are in the first group. They're only immigrating for the $$$.

Things have colors, life is not black and white you know.
