>>This is your opinion, and as of today, it is not a legally defined term that has been codified into US law.<<
I don’t think anything has been codified into US law regarding NBC. The 14th amendment dealt with NBC. From this blog you can read a lot of history on the topic:

The conclusion by the author there indicates place of birth is not relevant. But who the citizenship of the Father was. Of course that predates the 19th amendment. Now that women can vote, I think it’s reasonable to extend that same line of logic to the mother as well. The way I understand the NBC issue is that there is not one universal definition. Not by a long shot. The blog is an interesting read for anyone interested in the history of this topic.
Yes, blogs are the definitive authority on pretty much everything.
