If he was born in Hawaii then he doesn't have an immigration status, does he?
Sure he does, if he was adopted by Lolo them he lost his citizenship to become a citizen of Indonesia to go to school there. He could have EASILY gotten that back on returning to the US, but NOT as a Natural Born citizen. You can’t get that status back, and neither Indonesia nor the US recognize dual citizenship between those two countries.
Game over, Obama lost his Natural Born Status when he became a citizen of Indonesia.
