Of course Great Britain wouldn’t want him as a citizen but despite the fact that his father was a British citizen which makes Obama a British citizen too, he is, because his mother was an American citizen, also an American citizen.
Is he also a “Natural Born Citizen of the United States”? Yes, for two reasons, either one of which means he is a USNBC. First his mother at the time of his birth, was an American citizen. Second, he was born on American soil, in Hawaii. So he’s a USNBC.
Obama’s father was a British subject when Obama was born. That makes Obama a British subject too. He’s a dual national. Still is. He can apply for and get a British passport and keep his American passport.
His two daughters can do that too. Both of them can get two passports and use either one to enter and leave foreign countries.
