US Justice Department Files Case to Revoke American Citizenship of Nigerian Man Behind Multimillion-Dollar Tax Fraud Scheme
The United States Department of Justice has initiated legal proceedings to strip a Nigerian-born individual of his American citizenship, citing his involvement in a vast and sophisticated multimillion-dollar tax fraud conspiracy. The civil denaturalization complaint was formally filed and served in the U.S. District Court located in Baltimore, Maryland, targeting Emmanuel Oluwatosin Kazeem.
Announcement and Historical Context of the Case
This significant legal action was publicly announced by the DOJ in an official press release dated Wednesday, March 18, 2026. The case builds upon a prior criminal conviction from 2017, where Kazeem was found guilty on nineteen separate counts, including mail fraud, wire fraud, aggravated identity theft, and conspiracy to commit mail and wire fraud. For these crimes, he received a substantial sentence of fifteen years in federal prison.
However, in a notable development in December 2024, then-President Joe Biden commuted Kazeem's prison sentence after he had served only six years. This commutation was part of a broader clemency action affecting nearly 1,500 individuals who had been under house arrest following their release due to conditions related to the COVID-19 pandemic.
Official Statements and Legal Grounds for Denaturalization
"The Trump Administration will not permit wrongdoers to retain the U.S. citizenship that they were never entitled to in the first place," declared Assistant Attorney General Brett A. Shumate of the Justice Department's Civil Division. He further emphasized, "U.S. Citizenship is a privilege, and we will continue to ask courts to revoke a status that was obtained through fraud and deceit."
The newly filed legal complaint presents detailed allegations that Kazeem's extensive fraud activities, which occurred both before and after he was naturalized as a U.S. citizen, along with his deliberate concealment of these criminal acts, legally disqualified him from obtaining citizenship lawfully. The complaint also asserts that prior to the tax fraud scheme, Kazeem engaged in a sham marriage to secure permanent resident status and subsequently married another woman, further invalidating his eligibility for naturalization.
Detailed Examination of the Massive Fraud Conspiracy
According to court documents and evidence presented during Kazeem's criminal trial, the conspiracy began to unravel in May 2013 when a victim from Medford, Oregon, alerted the Internal Revenue Service (IRS) that fraudulent federal and state tax returns had been electronically filed using her and her husband's stolen personal identifying information, including Social Security numbers and dates of birth.
This report triggered a comprehensive IRS investigation, leading to the execution of search warrants at residences in Illinois, Maryland, and Georgia, as well as the examination of numerous email and instant messenger accounts utilized by Kazeem and his co-conspirators. During these searches, law enforcement agents made significant seizures:
- At a Chicago residence, approximately 150 prepaid debit cards and $50,000 in money orders were confiscated.
- In Maryland and Georgia, agents seized more than 50 electronic devices, 40 money orders exceeding $29,000 in total value, $14,000 in cash, and numerous prepaid debit cards containing over $12,000 in fraudulent tax refunds.
These investigative efforts conclusively identified Kazeem as the principal leader and mastermind behind the entire criminal operation. The scale of the conspiracy was enormous, resulting in the conspirators possessing stolen personal identifying information of more than 259,000 victims.
Methods and Financial Scale of the Fraudulent Operation
Kazeem acquired more than 91,000 stolen identities from a Vietnamese hacker, who had sourced them from a private database belonging to an Oregon-based company that provided pre-employment and volunteer background checks for thousands of clients. Kazeem systematically organized these identities into batches and distributed them among his co-conspirators, who then used the information to file fraudulent tax returns between 2012 and 2015.
In executing the scheme, Kazeem trained and directed his associates, including his younger brother, Michael Oluwasegun Kazeem, to utilize the stolen identities to obtain thousands of electronic filing Personal Identification Numbers (PINs). These PINs were used to bypass standard IRS authentication protocols. Over the course of the conspiracy, they successfully acquired over 19,500 E-File PINs.
Furthermore, Kazeem used victims' personal information to gain unauthorized access to their IRS transcripts, which contain highly sensitive personal financial data. The conspirators also employed prepaid debit cards registered with the stolen identities to receive direct electronic deposits of fraudulent tax refunds from the IRS.
The financial magnitude of the fraud was staggering. In total, Kazeem was directly linked to 10,139 fraudulent federal tax returns that attempted to secure over $91 million in illicit refunds. Of this amount, the conspiracy successfully received over $11.6 million. A significant portion of these funds was transferred out of the country, with at least 2,000 wire transfers totaling over $2.1 million sent to Nigeria. More than 700 of these transfers, amounting to over $690,000, were directly traced to Kazeem.
Lavish Expenditure of Illicit Proceeds and Asset Transfers
Kazeem utilized the substantial proceeds from the fraud to finance a luxurious lifestyle and significant investments. He made a nearly $200,000 down payment on a newly constructed house and purchased a $175,000 townhouse, both located in Maryland. His average monthly credit card payment during the peak years of the fraud, from 2012 to 2015, exceeded $8,300.
Additionally, Kazeem attempted to leverage his ill-gotten gains to develop a $6 million, 4-star hotel project in Lagos, Nigeria. In a move perceived as an effort to shield assets, in May 2015, he transferred the title of his townhouse to his sister in Nigeria for a nominal sum of $10 and also added her to the deed of his Maryland residence for the same token amount. He was arrested by authorities just one day after these transactions were completed.
Legal Proceedings and Ongoing Investigations
On June 20, 2018, Kazeem was formally sentenced to 15 years in prison and ordered to pay more than $12 million in restitution to the victims. His original criminal conviction was the result of a meticulous joint investigation conducted by multiple federal agencies, including IRS-Criminal Investigation, the U.S. Department of Health and Human Services Office of Inspector General, and the Federal Bureau of Investigation (FBI).
Investigative support was also provided by several other key agencies: the Treasury Inspector General for Tax Administration; the U.S. Postal Inspection Service; the U.S. Department of State; the U.S. Department of Homeland Security, specifically Homeland Security Investigations (DHS HSI); and U.S. Citizenship and Immigration Services.
Kazeem's criminal case was prosecuted by Assistant U.S. Attorneys Byron Chatfield and Gavin Bruce for the District of Oregon. The current denaturalization case has been investigated by DHS HSI and will be litigated by the Affirmative Litigation Unit of the Civil Division's Office of Immigration Litigation, marking a continued effort to hold individuals accountable for obtaining citizenship through fraudulent means.
