Except that Obama's father was subject to the jurisdiction of the United States. He was living here and had he broken the law then he could have been arrested, tried, and jailed.
BO’s father was a temporary resident alien and subject to laws, but he was completely subject the jurisdiction of the US, i.e. politically & militarily. Had a war broke out, he would have had to report back to the Brits, thus he was not a citizen and he had no intentions of becoming one. he was here to study so that he could serve inthe Kenyan government, which he subsequently did, so one could classify him as a sort of diplomat also, and in that case, it changes everything entirely aka being that Obama’s mother had not reached the age of majority, Obama would not have held anything other than british citizenship and thus to this day he could be an illegal alien resident.
