Nigerian Wiseman Oputa, living in Texas, United States has been jailed for three years by a federal judge in Houston.
The 25-year-old had pleaded guilty to a $1.3million wire fraud in April, using fake passports and romance schemes.
Investigators said Oputa used counterfeit passports to open bank accounts in the Houston area. The passports had his photo but different names and identification.
Prosecutors said he then then lured online victims into sending money to those accounts.
The scams ranged from bogus business deals and romance offers to false reports of money won and taxes needing to be paid to acquire the winnings.
Along with restitution, Oputa also will face deportation proceedings when he leaves prison.
