He left the Kingdom with his cousin, Prince Khalid bin Faisal Al Saud, for the United States and studied at the Institute of George Washington.

[citation needed] In 1957, King Saud made an official visit to Washington, D.C. carrying his three-year-old son, Prince Mashour, who was suffering an illness.

[3] U.S President Dwight D. Eisenhower tasked his personal physician to look after him at Walter Reed Hospital.

[4] In 1985, Prince Mashour was charged with conspiring to smuggle cocaine into Britain and spent two weeks in jail before he was granted 150,000 pound sterling bail at the high court in London.

Bail was refused after the prosecution told the court that Mashour had no diplomatic immunity[5] and was ordered to report twice a week to police until his trial.
