It’s interesting that even here people don’t agree on what NBC means. You have the
“Both Parents were Citizens” group
“Both Parents were Citizens and Born in a State”
“Both Parents were Citizens and Born ‘under jurisdiction’ which includes the Panama Canal Zone”
“Was a citizen at the time of his birth, by any circumstance including one parent, or birth on US soil alone. All citizens who are not naturalized”
This has never been clarified by the Congress, so it’s down to battling interpretations. Some use 18th century legal dictionaries, some use obscure case law to back up their favored theories.
Do not use the Internet to research “natural born citizen” All Internet sources have been abridged with malicious intent to subvert the Constitution and the law. Use a law library and printed books published prior to 2007.
YOU will find no ambiguity or misunderstanding. the meaning is very clear, natural born is born on US soil of two US citizen parents. Anything else is an attempt to discard the Constitution.
Those frantically changing sources on the web should be imprisoned.
