Investigations into the motivations and execution of the attacks led to the declaration of War on Terrorism that lead to ongoing military engagements in Afghanistan and subsequently Iraq. Clean-up and restoration efforts led to the rebuilding of Lower Manhattan, and federal grants supported the development of the National September 11 Memorial & Museum.Immediately after opening the hunt on Osama bin Laden, President Bush also visited the Islamic Center of Washington and asked the public to view Arabs and Muslims living in the United States as American patriots.[8]

Congress passed the USA PATRIOT Act, stating that it would help detect and prosecute terrorism and other crimes. Civil liberties groups have criticized the PATRIOT Act, saying that it allows law enforcement to invade the privacy of citizens and eliminates judicial oversight of law-enforcement and domestic intelligence gathering. The Bush Administration also invoked 9/11 as the reason to have the National Security Agency initiate a secret operation, "to eavesdrop on telephone and e-mail communications between the United States and people overseas without a warrant."[9]
On June 6, 2002, Attorney General Ashcroft proposed regulations that would create a special registration program that required males aged 16 to 64 who were citizens of designated foreign nations resident in the U.S. to register with the Immigration and Naturalization Service (INS), have their identity verified, and be interviewed, photographed and fingerprinted. Called the National Security Entry-Exit Registration System (NSEERS), it comprised two programs, the tracking of arrivals and departures on the one hand, and voluntary registrations of those already in the U.S., known as the "call-in" program. The DOJ acted under the authority of the Immigration and Nationality Act of 1952, which had authorized a registration system but was allowed to lapse in the 1980s because of budget concerns.[10][11] Ashcroft identified those required to register as "individuals of elevated national security concern who stay in the country for more than 30 days. source wiki
