After ten months, U.S. Border and Immigration Authorities took a fingerprint sample and discovered that he was the same person who had tried to enter the United States just before the September 11 attacks. Seizing the airport's CCTV surveillance recordings, the FBI claimed they were able to identify the car of Mohamed Atta at the airport, believed to be there to pick up Qahtani. Another military account stated that Qahtani was identified as someone who had previously been turned away due to visa problems – by fingerprints "taken in Southwest Asia".
