I'm not sure there's a "just" here: compared to peer countries, the US is either middle-of-the-pack[1] or significantly more accepting of immigrants[2] depending on which number you pick.

(This isn't to somehow imply that the US isn't hostile to its immigrants, because it is. But the question is whether it's more hostile.)
