Which would bring into play all the education he recieved as a student from out of the country. He basically got a free ride as a foreign student at Occidental. And just how did he pay for his college education? His parents were either out of the country, or when in country, very low paid Govt Employees. It is my opinion that he got foreign student scolarships which were more plentiful than academic scolarship for US students. Hence his sealing of school documents. If Frank Marshall were his father, he would have committed fraud, also not something he would like known.
Both could be true. I would not doubt the foreign scholarship thing. It would answer a lot of questions!
