I don't know.
In an interview with a Hawaii newspaper in June 1962, he told the interviewer he had not been back to Kenya for seven years...
On p. 50 of the immigration file, BHO Sr. signs in Nairobi, Kenya 29JUL59. So, either his statement (about a 7 yr absence) or the document at p. 50 is false.
Could be both. The teacher at the Maseno school is quoted as saying he left Kenya as soon as he completed school there in 1953. The question is, if he did, where did he go? Three or four years as an illegal somewhere in the US, quick trip home and back again, legal?
He had a relative, ‘Uncle Omar’ (now known as OBAMA ONYANGO) living in Boston. No problem.
He also wrote home to say he was working for an oil company and had married a white woman...who knows?
