Remember that you need not ever even have been to America to be a citizen. Second, America can decide who is a citizen according to their own laws, which is a bit of a conflict of interest.

So currently children of Americans are American, but there's no reason they couldn't arbitrarily decide that grand children, or great grandchildren are as well. Or if you want to be really silly, in theory they could grant citizenship to anyone if they amended the laws to do so.

So ive been given a status at birth by a foreign country that I have no wish for. They then grant me the privilege of paying them to renounce the status that they declared me to have!

Why thank you land of the free!
