Between 1990 and 1994. the ANC negotiated with the South African Government for the end of apartheid and the enfranchisement of black South Africans. In 1994. the ANC became a registered political party and Nelson Mandela was elected to be the first black president. Since the recognition of the ANC as a legitimate political party. several prominent black South Africans have been denied visas to enter the United States on the basis that they were considered to be inadmissible under the INA because they were members of a terrorist group. Nelson Mandela were considered inadmissible under this same law. In the past the Department of State has provided waivers to ANC leaders to enter the United States.
