Not necessarily, if the grad program was just cover for his being in the US
From Saudi newspaper:
A graduate student at the University of Colorado , studying linguistics, al Turki has lived in the United States since 1995.He's also running a business publishing Islamic books (Jihadi propaganda material?)Federal Court documents field by al Turki’ lawyers detail the investigation against him. They claim the Denver Joint Terrorism Task Force has had al Turki under a “full fledge investigation” suspecting “he is closely aligned to terrorists and may be providing material support to terrorism.”
His lawyers said he “adamantly and vehemently denies any links to terrorism.” They add he looks forward to being vindicated of all charges against him in court.
Of course the State Department is filth for not deporting them.
On September 12, 2001, every single one of the Saudi foreign students in the States should have been summarily deported.
And that should have been just the beginning.
