What about statutory citizens at birth? Such as, under 8 USC 1401, those born to two citizen parents, or even one citizen and one alien parent with restrictions, outside the country. They do not "go through the paces, take a test, raise your hand and swear". The parents have to file some documentation is all. The statute law says they are not naturalized, but some case law says they are, for Constitutional purposes. It's not so simple as you indicate.
