I’m not an expert, but I think you may be wrong a bit. I think if the mother is a natural born citizen who has lived her forever, any children born to her are natural born citizens. The same is true of the father, I believe.
If I’m wrong—well it won’t be the first time—but I have a situation like this in my family. The father became a naturalized citizen after the birth of his first child.
The children will be citizens but not natural born citizens of two citizen parents. Obama has admitted dual citizenship. That means he is not a natural born citizen.
I think you are a bit worng. The children you describe are native born citizens, and this caegory is NOT syononymous with natural born citizens. Most native born are also natural born, but to be natural born BOTH parent must be US citizens at the time of the child’s birth, and the child must be born in the Unties States of America.
The definition of NBC was generally accepted to mean that both parents were citizens when the child was born within the United States, and subject to the jurisdiction thereof. There is plenty of evidence that the framers of the constitution had this definition in mind. There is not dispute that such children meet the constitutional requirement once they are age 35.
As to other circumstances there are doubts, which have not necessarily been definitively defined by adjudication. The term natural born has deteriorated with popular usage, but that does not change what the law is.
The US Dept. of State's Foreign Affairs Manual Vol. 7 states the following: “the fact that someone is a natural born citizen pursuant to a statute does not necessarily imply that he or she is such a person for constitutional purposes”.
I have read enough on the subject to make up my mind what the constitutional requirement is. I do read additional articles when posted, in case there is something additional, that could change my mind, but so far there has been nothing.
To me the birth certificate is a moot point with respect to Obama’s eligibility. His father was a foreign national, and he has apparently been a citizen of 3 other countries. One could even say he is truly a citizen of the world, with all kinds of entangling and foreign influences and allegiance - not the unfettered citizen that the constitution requires. JMHO.
