Yes, I wasn't presuming otherwise, which is why I specified "less famously immigrant-friendly" instead of "less immigrant-friendly." I simply haven't heard as much about the immigration there even though I'm American, probably because Buenos Aires is a much larger city.
EDIT: Also, in case my "on a more serious note" didn't make it explicitly clear, that entire sentence about Boise was a joke.
EDIT 2: I might as well add that I looked this up [1], and Boise ranks 175th in immigration as a percentage of the metropolitan population or 101st as a percentage of cities, just among metropolitan areas (MSAs) or cities in the US. That's not exactly a "huge immigrant population" by my account.
