According to FBI director Robert Mueller and the 9/11 Commission, Omari entered the United States through a Dubai flight on June 29, 2001, with Salem al-Hazmi, landing in New York. He had used the controversial Visa Express program to gain entry. He apparently stayed with several other hijackers in Paterson, New Jersey, before moving to his own place at 4032 57th Terrace, Vero Beach, Florida. On his rental agreement form for that house, Omari gave two license-plates authorized to park in his space, one of which was registered to Atta.
