Mr Okeke, 32, admitted to American prosecutors that he was involved in computer-based fraud between 2015 and 2019.
Joshua Stueve, a spokesperson for the United States District Court for Eastern District of Virginia, told PREMIUM TIMES on Thursday evening that Mr Okeke could spend 20 years maximum penalty in an American jail.
Robert Krask, an American judge of the district, certified the guilty plea on Thursday morning to clear the paths for Mr Okeke's sentencing.
Mr Okeke and other alleged conspirators said to still be at large were accused of targeting American businesses in a probe led by the Federal Bureau of Investigation.
Over $11 million was said to have been traced to the ring, amidst claims that Mr Okeke allegedly used proceeds of his illicit dealings to build a business empire in Abuja and other parts of Nigeria.
