Hmmmm. Disturbing, isn't it? Did Superman ever naturalize? We know he was born elsewhere, and I don't recall him ever going through the legal process to be a resident alien. Heck, his planet exploded, so Superman doesn't even have a birth certificate, much less the long form.
Then again, if he is going to be hob-nobbing with the United Nations, as the comic indicates, he's hardly worthy of being an American anyway.
Wow, the more I think about it, perhaps it is better Superman heads on out. If he's not even willing to follow immigration law, how can he be trusted to protect the American Way?
