Is it enough that a migrant becomes self-supporting, and stays away from trouble with the law?
Migrants from different cultures should not all be expected to mirror a native ideal of their adopted homeland. (Surely many local-born people often fail to observe each tradition). Society would be far poorer without individual characteristics of a disparate population.
Sure some will study & enjoy local traditions, foods, and culture. But those who march to a different drumbeat (or don't march at all) are not signs of failure.
