I think the hypocrisy you're alluding to here is that coastal liberals are often NIMBYist, which has the direct effect of making housing expensive, which affects most people negatively, immigrants included. I'll agree with you on that one as being a problem, but I don't think it exactly fits into the class of issues you're talking about.
Also I think you're missing some nuance here, which is that the people arguing in favor of this would indeed do a lot more to admit emigrants/refugees here, it's just that they aren't in power and don't run the government. So they can't be hypocrites for advocating for something they genuinely would do if only they were able to.
But they're not in power and they aren't making the immigration decisions, hence it's not happening.
