Subsequent to going to a specialized school in Durban for a year, Nkosi filled in as a writer, first in 1955 for the Zulu-English week by week paper Ilanga lase ("Natal Sun") and afterward for the Drum magazine and as boss correspondent for its Sunday paper, the Golden City Post, from 1956 to 1960.
In 1961 Nkosi acknowledged a cooperation to consider reporting at Harvard University, and, thusly, he was banished from South Africa. From that time Nkosi composed for American, British, and African periodicals, including The New Yorker. A considerable lot of his basic articles were distributed in Home and Exile (1965), which turned into a standard hotspot for understudies of African writing.
The Rhythm of Violence (1964), a dramatization set in Johannesburg in the mid-1960s, handles the topic of race relations. Nkosi delivered the British Broadcasting Corporation (BBC) radio arrangement "Africa Abroad" from 1962 to 1965 and worked from 1965 to 1968 as abstract manager of The New African.
