In July 1990, the “Blind Sheikh,” Sheikh Omar Abdul-Rahman, was mysteriously able to enter the US and remain there despite being a well known public figure and being on a watch list for three years (see July 1990). 
In late October 1990, he travels to London, so he is out of the US when one of his followers assassinates the Zionist rabbi Meir Kahane on November 5, 1990 (see November 5, 1990). He returns to the US in mid-November under the name “Omar Ahmed Rahman” and again has no trouble getting back in despite still being on the watch list. [Washington Post, 7/13/1993] The State Department revokes his US visa on November 17 after the FBI informs it that he is in the US. [New York Times, 12/16/1990] In December 1990, Abdul-Rahman leaves the US again to attend an Islamic conference in Copenhagen, Denmark. He returns nine days later and again has no trouble reentering, despite not even having a US visa at this point. [Washington Post, 7/13/1993] On December 16, 1990, the New York Times publishes an article titled, “Islamic Leader on US Terrorist List Is in Brooklyn,” which makes his presence in the US publicly known. The Immigration and Nationalization Service (INS) is said to be investigating why he has not been deported already. [New York Times, 12/16/1990] Yet in April 1991, the INS approves his application for permanent residence. He then leaves the US again in June 1991 to go on the religious hajj to Mecca, Saudi Arabia, and returns on July 31, 1991. INS officials identify him coming in, but let him in anyway. [New York Times, 4/24/1993; Washington Post, 7/13/1993] In June 1992, his application for political asylum will be turned down and his permanent residence visa revoked. But INS hearings on his asylum bid are repeatedly delayed and still have not taken place when the WTC is bombed in February 1993 (see February 26, 1993). [Lance, 2003, pp. 105-106] Abdul-Rahman then goes to Canada around October 1992 and returns to the US yet again. The US and Canada claim to have no documentation on his travel there, but numerous witnesses in Canada see him pray and lecture there. Representative Charles Schumer (D-NY) says, “Here they spent all this time trying to get him out. He goes to Canada and gives them the perfect reason to exclude him and they don’t.” After the WTC bombing, the US could detain him pending his deportation hearing but chooses not to, saying it would be too costly to pay for his medical bills. [New York Times, 4/24/1993]
Abdul-Rahman will be involved in the follow up “Landmarks” plot (see June 24, 1993) before finally being arrested later in 1993. It will later be alleged that he was protected by the CIA. In 1995, the New York Times will comment that the link between Abdul-Rahman and the CIA “is a tie that remains muddy.” [New York Times, 10/2/1995]
March 10, 2000: Review of Counterterrorism Efforts Show Continued Worries; Sleeper Cells Feared
National Security Adviser Sandy Berger chairs a Cabinet-level meeting to review the wave of attempted terror attacks around the millennium. There are counterterrorism reports that disruption efforts “have not put too much of a dent” into bin Laden’s overseas network, and that it is feared “sleeper cells” of al-Qaeda operatives have taken root in the US. It is recommended that the FBI and the Immigration and Naturalization Service should begin “high tempo, ongoing operations to arrest, detain, and deport potential sleeper cells in the United States.” Some ideas, like expanding the number of Joint Terrorism Task Forces across the US, are adopted. Others, like a centralized translation unit for domestic intercepts, are not. [9/11 Commission, 3/24/2004] In July 2004, it is revealed that the Justice Department is investigating Berger for taking classified documents relating to this review effort out of a secure reading room in 2003. Most of the documents are returned, but a few apparently are lost. [Associated Press, 7/20/2004; Washington Post, 7/22/2004]
July 12-27, 2000: FBI Informant Files Stay Extension for 9/11 Hijacker Alhazmi; Filing Is Late
On July 12, two days before his visa expires, an I-539 application (dated July 7, 2000) to extend 9/11 hijacker Nawaf Alhazmi’s US stay is filed with the California Service Center (CSC) of the INS. [Nawaf Alhazmi, 7/27/2000] The I-539 form is not received by the CSC until July 27, 2000, and officially it is considered a late filing. [unknown: INS, 2002; INS email, 3/20/2002; 9/11 Commission, 8/21/2004, pp. 12, 25 
] The name of the form-preparer is redacted, but according to INS records, Alhazmi’s I-539 is submitted “in care of” Abdussattar Shaikh, an FBI informant Alhazmi is living with (see May 10-Mid-December 2000), and “appears to have been filed [sic] out by Shaikh.” [unknown: INS, 2002; Immigration and Naturalization Service, 5/26/2002] Alhazmi had been issued a one-year, multiple-entry visa on April 3, 1999, but when he arrived in the United States with Khalid Almihdhar on January 15, 2000, the immigration inspector approved a six-month stay for both of them (see January 15, 2000). Alhazmi’s I-539 visa extension will be approved on June 18, 2001, 11 months later (see June 18, 2001). No other extensions of stay will be filed by, or on behalf of, Alhazmi. [9/11 Commission, 8/21/2004, pp. 10, 12, 25 ]
Autumn 2000: FBI Informant Learns 9/11 Hiacker Living with Him Is Working Illegally, Doesn’t Tell His FBI Handler
Abdussattar Shaikh, an FBI informant who is also the landlord to two future 9/11 hijackers living in San Diego, California, learns that one of the hijackers is working illegally, but does not tell his FBI handler about it. Hijacker Nawaf Alhazmi lives in Shaikh’s house from May to December 2000 (see May 10-Mid-December 2000), and fellow hijacker Khalid Almihdhar lives there until June (see June 10, 2000). In the autumn of 2000, Alhazmi begins working at a local Texaco gas station (see Autumn 2000). In a 2004 interview with the 9/11 Commission, Shaikh will say that he becomes aware that a local man named Mohdar Abdullah helped Alhazmi get a job at the gas station. Shaikh will say he is disturbed about this because he knows Alhazmi doesn’t have a work permit. He is concerned that the Immigration and Naturalization Service (INS) will hear about this, and that it will reflect negatively upon himself. He warns Alhazmi that he could be deported. But Alhazmi says he is not worried because Abdullah has been working at the gas station for some time with other illegal workers. Shaikh never tells his FBI handler Steven Butler about this, and apparently even asks Alhazmi not to discuss his employment at the gas station with him. [9/11 Commission, 4/23/2004] It will later turn out that both the manager and the owner of the gas station have already been investigated by the FBI about Islamist militant links (see Autumn 2000), and some of the other employees at the gas station, including Abdullah, may have foreknowledge of the 9/11 attacks (see Early 2000 and Late August-September 10, 2001).
March 28, 2001: Florida INS Official Alleges Middle Eastern Immigrants with Possible Terrorist Ties Are Bribing Their Way into US
Mary Schneider, a veteran Immigration and Naturalization Service (INS) employee in Orlando, Florida, writes to Attorney General John Ashcroft to warn that a ring of corrupt INS officers is taking bribes from illegal Moroccan and Egyptian immigrants. She is concerned some of these illegal aliens let into the country could have ties to terrorist organizations, and calls for an investigation. Schneider started complaining to her supervisors in 1998 and claims she was retaliated against by management. In May 1999, she wrote to the FBI’s anti-terrorism joint task force in New York to warn of the possible terrorist ties of some of the illegal immigrants allowed into the country by her office. She says some of them could be linked to Ihab Ali Nawawi, an Orlando taxi driver arrested in 1999 for his ties to Osama bin Laden (see May 18, 1999). It is not known what actions, if any, were taken as a result of her warnings. [New Times Broward-Palm Beach, 11/8/2001]
May 2001: Report Warns of Al-Qaeda Infiltration from Canada
US intelligence obtains information that al-Qaeda is planning to infiltrate the US from Canada and carry out an operation using high explosives. The report does not say exactly where, when, or how an attack might occur. Two months later, the information is shared with the FBI, the INS, the US Customs Service, and the State Department, and it will be shared with President Bush in August. [US Congress, 9/18/2002; Washington Post, 9/19/2002] This information could come from captured al-Qaeda operative Ahmed Ressam, who warns around this month that al-Qaeda leader Abu Zubaida has been seeking Canadian passports as part of a plot to attack the US, possibly by planting explosives in several US cities (see May 30, 2001 and May 2001). [Calgary Herald, 4/3/2002]
May 16, 2001: Two 9/11 Hijackers Refused Entry to Bahamas; US Immigration Mistakenly Thinks They Have Left US
9/11 hijackers Satam Al Suqami and Waleed Alshehri attempt to enter the Bahamas, but are refused entry because they do not have visas. They fly from Fort Lauderdale, Florida, to Freeport, Bahamas, where they have a hotel reservation for three nights, but are turned away by the local authorities and have to return to the US. The 9/11 Commission will speculate that the trip is an unsuccessful attempt to extend Al Suqami’s visa, which is due to expire within days (see May 20, 2001). However, as they are refused entry to the Bahamas, they are regarded as never having left the US and Al Suqami is not given an extension to his permitted length of stay when he returns to Florida. Alshehri is stopped by US customs during pre-clearance in the Bahamas, but he is not searched and his luggage is not X-rayed; the inspection lasts one minute. There is an error regarding Alshehri’s port of departure on his INS record which indicates that he leaves from Fall River, Massachusetts, not Fort Lauderdale, Florida. The two hand over their departure records when they leave, but, since they do not enter the Bahamas, they do not receive new arrival records when they return to the US. This causes INS records to incorrectly indicate that the two are outside the country from this date until 9/11. [9/11 Commission, 8/21/2004, pp. 23, 41 ]
May 30, 2001: Yemenis Are Caught Taking Suspicious New York Photos
Two Yemeni men are detained after guards see them taking photos at 26 Federal Plaza in New York City. They are questioned by INS agents and let go. A few days later, their confiscated film is developed, showing photos of security checkpoints, police posts, and surveillance cameras of federal buildings, including the FBI’s counterterrorism office. The two men are later interviewed by the FBI and determined not to be a threat. However, they had taken the pictures on behalf of a third person said to be living in Indiana. By the time the FBI looks for him, he has fled the country and his documentation is found to be based on a false alias. In 2004, the identity of the third man reportedly still will be unknown. The famous briefing given to President George W. Bush on August 6, 2001 (see August 6, 2001), will mention the incident, warning that the FBI is investigating “suspicious activity in this country consistent with the preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York.” When Bush’s August 6 briefing will be released in 2004, a White House fact sheet will fail to mention the still missing third man. [New York Post, 7/1/2001; New York Post, 9/16/2001; Washington Post, 5/16/2004] In 2004, it will be reported that Dhiren Barot (a.k.a. Issa al-Hindi or Issa al-Britani), an alleged al-Qaeda operative in British custody, was sent to the US in early 2001 by Khalid Shaikh Mohammed to case potential targets in New York City. He headed a three-man team that surveyed the New York Stock Exchange and other buildings. While there are obvious similarities between the two Yemeni man with an unknown boss and Barot with two helpers, it is not known if the two cases are related. [New York Times, 8/7/2004]
June 18, 2001: 9/11 Hijacker Alhazmi’s US Stay Renewed despite Expiration, Late Filing, Unlawful Presence, and Indicator of Islamic Extremism in Passport
The INS extends future 9/11 hijacker Nawaf Alhazmi’s permitted stay in the US, 11 months after he filed a late application to extend it (see July 12-27, 2000). The INS should not grant the extension due to the late filing, but does so anyway. It is unclear why it has taken 11 months to process the application. The approval retroactively extends Alhazmi’s stay for six months, from the date it originally expired until January 14, 2001. While his unlawful US presence after July 14, 2000 is retroactively legalized, Alhazmi’s presence after January 14, 2001 remains unlawful, and no other applications for extensions will be filed. [Immigration and Naturalization Service, 2002; INS email, 3/20/2002; Immigration and Naturalization Service, 5/26/2002; 9/11 Commission, 8/21/2004, pp. 12, 25 ] An INS report will note, “The application shouldn’t have been approved because it was filed 13 days late.” However, an official, whose name will be redacted, will write in an INS e-mail: “Per [redacted]. This is a common occurrence that is within the adjudicator’s discretion to forgive a late filing, if it is brief and the applicant has a good story.… How do you suppose the press may spin this, and more importantly, how will the INS defend itself?” [Immigration and Naturalization Service, 2002; INS email, 3/20/2002] Alhazmi never receives notification of the extension, as the notice will be returned as undeliverable on March 25, 2002. [9/11 Commission, 8/21/2004, pp. 25 ] His passport contains an indicator of Islamist extremism used to track terrorists by the Saudi authorities (see March 21, 1999). The 9/11 Commission will comment that this extension is “[y]et another opportunity to spot the suspicious indicator,” but US authorities fail to do so. [9/11 Commission, 8/21/2004, pp. 12 ] The precise state of US knowledge about the indicator at this time is unknown (see Around February 1993). The CIA will learn of it no later than 2003, but will still not inform immigration officials then (see February 14, 2003).
July 5, 2001: Counterterrorism ‘Tsar’ Clarke Warns Domestic Agencies of ‘Something Spectacular’ Planned by Al-Qaeda
At the request of National Security Adviser Rice and White House Chief of Staff Andrew Card, counterterrorism “tsar” Richard Clarke leads a meeting of the Counterterrorism Security Group, attended by officials from a dozen federal agencies, including the Immigration and Naturalization Service (INS), the FAA, the Coast Guard, the Secret Service, Customs, the CIA, and the FBI. The CIA and FBI give briefings on the growing al-Qaeda threat. [Washington Post, 5/17/2002; Time, 8/12/2002; 9/11 Commission, 7/24/2004, pp. 258] Then Clarke later recalls saying, “You’ve just heard that CIA thinks al-Qaeda is planning a major attack on us. So do I. You heard CIA say it would probably be in Israel or Saudi Arabia. Maybe. But maybe it will be here. Just because there is no evidence that says that it will be here, does not mean it will be overseas. They may try to hit us at home. You have to assume that is what they are going to do.” [Clarke, 2004, pp. 236] Two attendees later recall Clarke stating that “something really spectacular is going to happen here, and it’s going to happen soon.” One who attended the meeting later calls the evidence that “something spectacular” is being planned by al-Qaeda “very gripping.” [Washington Post, 5/17/2002; Time, 8/12/2002; 9/11 Commission, 7/24/2004, pp. 256] Clarke directs every counterterrorist office to cancel vacations, defer non-vital travel, put off scheduled exercises, and place domestic rapid-response teams on much shorter alert. However, there is very poor follow up to the meeting and the attendees don’t share the warnings with their home agencies (see Shortly After July 5, 2001). By early August, all of these emergency measures are no longer in effect. [CNN, 3/2002; Washington Post, 5/17/2002]
