9/11 hijacker Ziad Jarrah arrives in the US for the fifth time and is admitted at Newark as a business visitor, receiving a six-month stay. This is unusual, as inspectors usually give business visitors one to three months, depending on the port of entry, and six months only when the visitor can document the purpose of the stay, which Jarrah apparently does not do. Jarrah actually should not be admitted at all because he is out of status—he breached immigration rules by taking a flight training course despite entering the US as a tourist—but this is apparently not noticed (see June 27-28, 2000).
