Here, I believe, is where we come into conflict...
A natural born citizen is born a U.S. citizen and has no need of a legal process to establish citizenship...

How many citizen parents, in your opinion, does a person need to have in order to be a natural born citizen?

I contend that two citizen parents are needed, not just one. What say you?

[allmendream]

One need only be born a U.S. citizen under U.S. law (which should always be in accordance with natural law) to be a natural born citizen.

So where in the U.S. Constitution does it mention any fourth category of citizenship?

There are only those at the time of adoption.

Those that are natural born.

And those that must be naturalized.
