Those immigrants were also irrevocably removed from their homelands. They couldn't go back twice in a lifetime, much less twice a year. They couldn't send all their money home (at least I don't see how, and they probably couldn't afford to). They couldn't just save up to retire back there when they don't need a job any more. So that's part of your assimilation.
And you know do or do not get into the whole "white" thing. I don't see any problems with European immigrants, still. You get a little crime and corruption from the Eastern Europeans, but some of that is Jewish. Actual Poles and Ukrainians and Russians seem fine to me. And the US had a preference for Western European immigrants which made sense too. Today, I say cut it all off, because if we invite Europeans we'll get "Europeans".
