If he was a foreign student he could only attend a US college on a foreign student visa. No one has been able to find a foreign student visa issued to Barack Obama, II but his father’s foreign student visas were released under Freedom of Information Act requests.
I think you know very well that Obama’s passports and papers have been thoroughly messed with, and destroyed when that was more convenient. And one of the guys who did that for him in the State Department was subsequently killed. And his academic records have all been withheld and destroyed.
Moreover, although we don’t know for sure that he was born in Kenya, there is plenty of evidence that both the short-form COLB and the long-form COLB that he released only on-line, and not as an actual piece of paper, are forgeries. Indeed, the COLB he released after the raid on bin Ladin is not even a careful forgery. But of course the press and the Republicans and the rest pretend that the matter is settled.
There was a thorough discussion of these issues earlier, and it’s obvious that Obama’s so-called birth certificate is a fake.
Moreover, Obama became an Indonesian citizen when he was adopted by his stepfather, thus giving up any right to American citizenship, and there is no evidence that he ever applied again to be an American.
Arpaio may have been fooled by pretended further details. But he did a good job laying out the facts of the forgeries some time ago. But of course the press isn’t interested, nor are the Quisling Republicans.
