US law does not require both parents be US citizens. The Naturalization act of 1790 does not require both parents be US citizens.
... “the children of citizens of the United States that may be born beyond Sea, or out of the limits of the United States, shall be considered as natural born Citizens: provided, That the right of citizenship shall not descend to persons whose fathers have never been resident in the United States”.
Notice the open nature of the wording. It is not restrictive in that it does not require BOTH parents.
Naturalization act.
That is an act of congress.
Minor vs Happersat, the judge states that all born outside of the states are naturalized, by will of congress.
This ruling has now stood as fact for more than 100 years.
In the opinions, they state citizenship is not passed by blood line outside the states.
So Ted has a big problem.
