OK, so just for the record, then, is Hamdi currently a citizen? If he is, then that means Congress can't change that fact, right?

(Sorry if it seems like I'm asking a dumb question; I just wanted to make sure we're all on the same page on this matter)

YES

NO. Congress could change the law on how citizenship of naturalized citizens gets revoked. That could in the future cause him to lose his citizenship, although there is surely some 'ex post facto' nature of the rule, so that they cant simply change the law on naturalization itself and *retroactively* apply it to citizens.
