A 32-year-old Nigerian, Atuchukwu Onyeanusi, has been sentenced in the United States after being found guilty of fraud-related offences involving the use of false identity and immigration documents to secure employment.
The sentencing was delivered by U.S. District Judge Camela C. Theeler in a federal court in South Dakota, according to the U.S. Attorney’s Office for the District of South Dakota.
Onyeanusi received a sentence of time served, less than six months in detention, followed by one year of supervised release. He was also ordered to pay a $1,000 fine alongside a $100 special assessment to the Federal Crime Victims Fund.
Court records show that he was initially indicted in December 2025 by a federal grand jury on multiple counts, including visa fraud, use of false documents, and aggravated identity theft.
He later entered a guilty plea on February 27, 2026.
Authorities stated that Onyeanusi, who held lawful permanent residency in the United States, was stopped by law enforcement in Oklahoma on November 10, 2025, for a traffic violation.
During the stop, officers discovered a Texas commercial driver’s licence bearing his photograph but another person’s identity. He was also found in possession of an employer identification card linked to Great Plains Tribal Leaders’ Health Board in South Dakota, where he was allegedly listed under a false name as a “Cyber Threat Analyst.”
Investigators further revealed that he used a fake Social Security card and fraudulent documents to gain employment, and also falsely declared U.S. citizenship on immigration-related employment forms.
The U.S. Attorney’s Office said the prosecution formed part of “Operation Take Back America,” a federal initiative aimed at tackling immigration-related crimes and transnational criminal activity.
The case was investigated by Homeland Security Investigations alongside the Craig County Sheriff’s Office in Oklahoma and prosecuted by Assistant U.S. Attorney Benjamin Schroeder.
