When he was finished at high school in Lincoln in 1920, he went back to Mexico, to ask his father to pay for him to go to university. Hughes' father was a lawyer and a wealthy landowner. He could afford to send his son to university but he made difficulties about it. He said that Hughes could only go to university if he went overseas and studied engineering. Hughes wanted to go to a university in the US. After a time, they made an agreement that he should go to Columbia University but study engineering, not an arts degree. He went to Columbia in 1921 but left in 1922, partly because of the racism in the university.
