Religion is somewhat a concern, but it's completely dwarfed by issues around the religiosity of non-immigrant populations.

Speaking a different language at home is a really good thing. Kids are going to pick up English through immersion anyway, so they're going to turn out bi/multilingual. That's great.

So, most of my extended family is from the Middle East, mostly Christian with some Muslim in-laws. My understanding is that those immigrant groups are far more religious and traditional than the average non-immigrant (that is, not just counting the extreme parts), which of course I'm fine with cause they're my own. But I'm not sure what you're expecting from them.

I'm not expecting anything from them! Just pointing out that the actual problem with religion in, say, the US, is white Christian nationalism, with fundamentalist Islam a distant second.

Oh, yeah. But anything that's only 1% won't have much effect.

(By the way, I do think immigrants integrating into society is a moral good! I'm very left-wing and it's one of my most conservative beliefs. But the burden of that should be on the hegemonic/native-born population, not on immigrant communities.)
