Nigerian Nobel Prize-winning author Wole Soyinka has revealed that the United States revoked his visa and imposed a travel ban on him. The 91-year-old literary icon, who was awarded the Nobel Prize in Literature in 1986, disclosed that the US consulate requested his passport to cancel his visa in person, citing unspecified new information. Soyinka described the invitation as a “rather curious love letter from an embassy” during a press conference on Tuesday. He advised organizations planning to invite him to the US to “not waste their time.” The US Embassy in Nigeria declined to comment on individual cases. Soyinka, who previously held US permanent residency, famously tore up his green card in 2016 to protest Donald Trump’s election. He humorously remarked that the card had “fallen between the fingers of a pair of scissors and got cut into pieces.” Soyinka has been a vocal critic of Trump’s immigration policies, linking the visa revocation to his outspoken remarks. He recently compared Trump to Uganda’s infamous dictator Idi Amin, calling him “Idi Amin in white face.” When asked if he would return to the US, Soyinka quipped, “How old am I?” The US State Department recently tightened visa policies for Nigeria and several other African countries, reducing validity periods significantly.
