U.S. Orthodox Jews are overwhelmingly native-born. Not immigrants. Their conservatism should be self-evident. There were a bunch who came over from middle eastern states in the postwar era, but that era is done (really the 1979 Persian diaspora was the last).

I don't think U.S. Israelis lean conservative. They're generally secular and trying to get away from Israeli religiosity or military service. Half the Israelis I meet in NY came to avoid the draft. A ton are undocumented and often moneyed, here only for their 20's. If they don't get papers or bigtime success here, they go home and settle down with a nice Jewish girl, having sown their wanderlust and wild oats.
