What I have seen, is Sicilians coming over to the US, and sticking with their own kind. And by their own kind, I mean other immigrants, not sicilian-americans.
They don't trust anyone as a rule, though. Not even each other.
That is being smart though when you think about it. If I moved to Sicily I'd want to be around other Americans just to feel somewhat safe. I wouldn't trust the bastards further than I could throw them and I'm not saying Sicily is dangerous but that is what would make me feel safer than just plowing through town not knowing what is what.
