There you hit it on the head ~ “permanant residence” ~ Obama’s father was a foreign student here under a student visa. He was NOT a permanent resident, nor did he intend to be one. In fact, he wanted to be a big cheese in Kenya, returned there, and did well (compared to others, although not as well as he wanted to do). Man was killed in an auto accident in an age when only the richest and most powerful people in African had an opportunity to do so.
