U.S. President George Bush Tuesday signed a bill that allows Nelson Mandela to enter the United States without special clearance.
The measure officially removes Mr. Mandela and his African National Congress from a U.S. terror watch list.
The former South African president may now visit the United States without the U.S. secretary of state having to certify that he is not a terrorist.
Mr. Mandela was placed on the list because of his work with the African National Congress (ANC), which fought to end white minority rule in South Africa.
Mr. Mandela spent 27 years in prison for his work with the ANC to fight apartheid rule in South Africa.
The Nobel Peace Prize winner turns 90 on July 18.
