It isn’t easy being an Alien in the United States (or anywhere on Earth). How can a real Alien (an extraterrestrial) prove who he-or-it is, or what? There are no passports for Aliens. If an Alien has an unfortunate accident and crashes on this planet he (It) is out of luck. No way to establish residency. No rules apply. The unfortunate Alien will be ignored — no one will even bother to test “him” or use “him” as a guinea pig — it won’t happen because earthlings are generally apathetic. The human view of the world/universe stops just beyond the body-sack they inhabit.
