Wrong issue. A minor cannot be stripped of American Citizenship by a foreign adoption. I believe that has been established by case law.
IMHO, there are 2 issues:
(1) If were born in the US, he would be a citizen, but not "Natural Born," because BHO, Sr. was not a US citizen. In fact, Jr. might have a "Dual Citizenship" claim. Still not "Natural Born."
(2) If BHO, Jr. was born outside of the US, the whole issue becomes complicated indeed. However, he still might legally claim dual citizenship. Still, no cigar on the "Natural Born" issue.
Unfortunately, the guys who wrote the US Constitution were unfamiliar with the term "CHUTZPAH," and although they wrote a fairly clear direction, they neglected to include any mechanism for insuring that it was followed.
N"Natural Born" means, IMO, born to two American Citizens. It has been established that the birth of a "Natural Born" American citizen can occur outside of the country. The operating principle is "Two American Citizens," inside the country or out.
Actually I think the term natural born that was used at the time of Obama’s birth is at least one parent be an American and that parent has to be at least 18 (I believe his mom was 17). But the question is whether he was born in Hawaii or not. If he was, then the one American parent’s age does not come into play. If born outside the U.S. then the parent’s age comes into play. That is why they want to find out if he was born outside the U.S. or not.
There should have never been any question about McCain (though some in the press raised it) because he was born to two American parents and the Panama canal zone at the time he was born was American property.
