wanted to join Atta, al-Shehhi, and Jarrah, but were denied U.S. visas several times. Bin al-Shibh's visa was denied since he was a Yemeni citizen. He made several more attempts to obtain a U.S. visa. One such attempt was a $2,200 deposit he sent to the Florida Flight Training Center as a down payment for a similar training course taken by Ziad Jarrah. He used that application as a basis for a new attempt to get a student visa, rather than the visitor visa he previously had sought. On another occasion, he arranged for several thousand dollars to be deposited in his Yemeni bank account, to demonstrate financial wherewithal.

In the spring, al-Hazmi told a friend that someone was going to wire $5,000 to him, and that the money would come from Saudi Arabia. Al-Hazmi told his friend that he had no account. The friend allowed him to use his account, and later found that the money came from a man named "Ali", and that it did not originate in the U.S. The two wanted to take flight lessons, which is why they
