The Congress has decided that a person born on a military ship or military base to two US citizens is a natural born citizen. Meaning if you’re on that Navy (or Coast Guard) ship in Canadian waters, and both your parents are US citizens, you are a Natural Born Citizen. And you also hold Canadian citizenship.
Look, the issue is you’re trying to restrict a person’s eligibility based upon what a 3rd party (another nation) decides to do. If the UK considered you a citizen, and granted the full rights thereof, are you suddenly prohibited from being President? NO! Because you haven’t renounced what you originally had.
The issue of dual citizenship is irrelevant, and is a serious distraction and bad avenue of argument over President Obama’s standing as a natural born citizen. None.
I believe your statement is false. Please provide a link.
To my knowledge, Congress has only found such persons to be citizens under Congresses statutory naturalization power, not natural born citizens. Congress on its own can't change the definition of NBC in the constitution and only SCOTUS can clarify what that means. Numerous efforts in Congress have been attempted to re-define NBC, but none have passed.
Senate resolution 511 attempted to declare McCain a natural born citizen in a non-binding resolution, but it was just that...non-binding!
See also the link in the story at the top of this string detailingn the history of failed Congressional attempts to re-define NBC:
If you have citizenship from two different country's, you have what the framers wanted to prevent (post grandfather clause) with the inclusion of the NBC requirement for the Commander in Chief...divided loyalties.
If one is born in country, to two citizen parents and never obtains (or is "granted") citizenship by another sovereign...that person will have no loyalties "owed" to another country.
It should be clear to most why the United States would/should NEVER want a Commander in Chief of the armed forces to have multiple allegiances...loyalties owed to another country.
Dual citizenship/dual alligiences wasn't a good idea for the CinC in 1787...nor is it a good idea in todays world.
