You're conflating the rationale for the exclusion of those separate subgroups. Felons are not excluded for being "unfriendly" (agreeable shorthand). They are excluded because of a (perceived) risk to public safety, demonstrated by their conviction for criminal behavior.[1] To make a similar claim about foreign-born residents would be even more flagrantly xenophobic and racist than merely calling them unfriendly.

[1] Keeping in mind that especially for non-violent and non-vehicular convictions I don't buy into the whole "felons are bad, mmmkay" business, nor the argument that felons chose to exclude themselves from civil society by their own actions, but that's not the discussion we're having.
