On 5 June 2002 United States Attorney General John Ashcroft announced the National Security Entry-Exit Registration System (NSEERS). The initiative captures and archives biographic data and images of the faces and fingerprints of select foreign nationals visiting or residing in the United States on temporary visas. Because all of the 19 individuals involved in the 11 September 2001 hijackings entered the United States on valid temporary visas, NSEERS was promoted as a program to prevent future terrorist attacks and enhance border security through rigorous documenting and monitoring of visitors to the United States.
