There is nothing in US law to support this assertion. That is why lawsuits alleging this always get tossed. There are only two types of US citizens, natural born and naturalized. This assertion that there are additional types, like "Citizen at Birth" has no support.
Did you read the article?
It’s too bad the constitution was tested by the “historic” first black POTUS - a constitutional law “professor”. They really did a number on us. Now look at us, you don’t even have to be born here anymore and you can have dual citizenship and still be deemed eligible by your supporters.
We’ve let personal motives overcome the intent of the constitution.
I've been doing some digging today and it's obvious to me that the question of Cruz's citizenship was completely governed by the provisions of the 1952 immigration and naturalization act. Under that act's provisions he would have to fulfill certain residency requirements as a young adult, or his citizenship would go bye-bye.
Natural born citizens' status are not controlled by statute. It's a fact of nature.
If Ted Cruz was a natural born citizen, he would have been a citizen regardless of what our immigration and naturalization statutes require.
He would have been a natural born citizen no matter when in American history he had been born.
Which quite obviously isn't the case. There's no way he would have been even a citizen from birth throughout most of American history, because of the way our statutes read.
I repeat my initial question: How can a Constitutional requirement be changed by mere statute?
