The Kenyan independence movement picked him to be groomed for a leadership position and nominated him for an American-sponsored scholarship in economics. He wrote to 30 colleges and universities seeking a scholarship: the University of Hawaii was the one that replied.  In the September of 1959,  he left his pregnant wife and their new son to attend the University of Hawaii becoming the first African student on campus.

At Harvard Barack Obama Sr. obtained a masters degree in economics and later returned to Kenya to take a government position. 
Ann Dunham filed for divorce in January 1964  and would go on to marry an Indonesian man, Lolo Soetoro. The couple and the young Barack Obama moved to Jakarta, Indonesia in 1967.
