A former minister of finance Ngozi Okonjo-Iweala has taken American citizenship more than three decades after she studied in the United States.
Mrs Okonjo-Iweala, who is running for the office of the director-general of the World Trade Organisation (WTO), took US citizenship in 2019, her spokesperson told Bloomberg on Wednesday.
According to Bloomberg, most of the candidates battling for the position with the Nigerian boast of dual citizenship, which experts believe may boost their chances at getting the much-coveted job.
The other candidates for the position, such as Jesús Seade Kuri, is Mexican and Lebanese.
Also, Amina Mohamed, a Kenyan minister, is also Somali and Abdel-Hamid Mamdouh is both Swiss and Egyptian.
Although Okonjo-Iweala arrived in the US in the 1970s to attend Harvard University where she raised four children and worked for 25 years at the World Bank she, however, refused taking up its citizenship.
This affected her when she ran for the president of the World Bank in 2012 because she was not backed by the US, losing the seat to Korean-American Jim Yong Kim.
