So your parents took care of that when you were young? Maybe you are really not a US citizen afterall? Wouldn’t that be a kicker of a surprise. Are you too old to apply for DACA? :)
I don't remember it personally but presumably I was born in a prominent hospital. (Funny story, maybe when I was 24 or so I went to see a doctor and the nurse recognized my name... said "I was the one who slapped you when you were born" Maybe she says that to all the guys).
