A legal luminary, Mr Kayode Ajulo cautioned the Nobel Laureate on Thursday in Abuja.
Soyinka had issued the threat to destroy his American Citizen’s Card before voting begun in the keenly contested election between Trump and Hillary Clinton.
The election that produced the Republican candidate as the U.S. President-elect had sent some waves of shock to most countries.
Reacting to the threat, Ajulo warned Soyinka that he risked a jail term of three to seven years, if he (Soyinka) cut his green card.
“Under the American law losing or having your U.S. green card destroyed can be a serious problem,’’ he said.
He said legally such is tagged as wishful destruction of government’s property.
Ajulo said green cards or passports are valuable documents and should be looked after it with care.
He said mishandling of passport could stop you from travelling not to talk of destroying green card.
