Interesting, I'd like to hear more about it, if you are willing to share.Some of them don't care for sure, and are deliberately trying to make Little Arabia/Africa in parts of their respective host countries.
However, a significant number of them *do* care, especially once they realize that their 'peers' will often have withhold crucial information from them. I myself have met and known two couples, one pair from Iran and one from Somalia, where they at some point realized that living in the 'ghetto' did nothing for them, except isolated them from the rest of the population. In both cases they were surprisingly ignorant of even very basic things in relation to how we 'do' things in this country. It was quite interesting to see them break free of their former bonds and notice the illumination on their faces, when the proverbial light bulbs went off at regular intervals.
More details on request.
