I mean, there are plenty of wealthy immigrants here, but I would say there are probably more immigrant families from regular or (relatively) poor families around. Like, people with a regular income who are working a regular job, not your average finance expat from an English-speaking country on an all-expenses-paid expat package plus a neat half million bucks per year salary on top.

That said, the non-expat immigrants I know are overwhelmingly from eastern European countries, so I wouldn’t be surprised if the acceptance policy is biased against non-Europeans. You don’t see many average working-class Americans around here unless they married a Swiss person.
