I’m not so sure about the merits- see my above post- looks like the supreme court has pretty much decided possibly that citizen by birth needs no naturalization process, and should be considered NBC- but We’ll see how it plays out in court if it ever gets there- if the court refuses the case, it will likely be because of the previous cases which found that citizens by birth are NBC
American Indians were made citizens by Congress in the Indian Citizenship Act of 1923. If that is when they became eligible to run for potus, then scotus is ceding a lot of power to Congress. I don’t think they’ll do that.
But even more problematic is the Cruz nbc question. If Cruz had stayed in Canada would his children be nbc? And their children?

They just need to go to America and get the required years of residency first.
