US State Dept: Warns of Nigeria Business Executive Detention Risk

• The US State Department has warned American business executives about the risk of arbitrary detention during routine business trips to Nigeria.
• This risk is particularly high for companies involved in regulatory investigations, tax disputes, or other disagreements with Nigerian authorities, as detailed in the 2026 Nigeria Investment Climate Statement.
• The detention of former Binance executive Tigran Gambaryan for eight months on money laundering and tax evasion charges serves as a key example of these dangers.
• Nigerian authorities are also alleged to use coercive exit bans, watch lists, and scrutinize business visas to pressure foreign firms and travelers.
• The US government advises businesses to update risk assessments due to these heightened risks, which also include reported airport "shakedown" efforts targeting wealthy passengers.

Lawyers and compliance officers advising foreign businesses operating in or traveling to Nigeria must immediately review and update risk assessments, particularly regarding regulatory investigations, tax disputes, and visa compliance, to mitigate the heightened risk of arbitrary detention and travel restrictions for executives, as highlighted by the US State Department and the Binance executive case.

The United States government has issued a significant advisory to American business executives and investors, cautioning that standard commercial travel to Nigeria carries a heightened risk of detention. This warning, detailed in the latest 2026 Nigeria Investment Climate Statement from the US Department of State, specifically highlights situations where companies are embroiled in regulatory investigations, tax disputes, or other disagreements with Nigerian authorities. The report underscores a concerning trend where routine business engagements can quickly escalate into a foreign executive's arbitrary detention in Nigeria.

Concerns articulated by the US government include the alleged deployment of arbitrary detention, travel restrictions, and immigration enforcement as tactics to exert pressure on international businesses operating within Nigeria. The State Department explicitly stated that US businesses should be aware that a typical business trip could lead to detention if their firm is under official suspicion or facing charges from Nigerian agencies. This advisory serves as a critical update for those navigating the Nigeria investment climate.

A prominent example illustrating these risks is the case of Tigran Gambaryan, an American citizen and former United States Internal Revenue Service agent, who was an executive for the cryptocurrency exchange Binance until his resignation in June 2025. In February 2024, Gambaryan and another senior Binance executive were detained shortly after their arrival in Abuja for scheduled meetings with Nigerian officials. Their passports were confiscated, and both individuals were initially held without formal charges in a government guest house, though one executive subsequently managed to escape.

Gambaryan was later transferred to Kuje Prison in Abuja, where he faced serious allegations. The Economic and Financial Crimes Commission brought money laundering charges against him, while the Federal Inland Revenue Service, now known as the Nigeria Revenue Service, filed tax evasion claims. He remained in detention for approximately eight months while judicial proceedings unfolded. Ultimately, the charges against Mr. Gambaryan were withdrawn in October 2024 on humanitarian grounds, an incident the State Department has explicitly cited as a stark warning to foreign executives regarding the potential ramifications of regulatory disagreements with Nigerian authorities.

Beyond the high-profile Binance incident, the US report details a broader pattern of coercive measures employed by Nigerian authorities. It alleges that Nigeria has historically utilized exit bans and arbitrary detention as leverage in commercial or regulatory disputes, often to compel multinational firms to resolve issues, provide data, or make financial concessions. Furthermore, entry and exit restrictions, commonly referred to as "watch lists," are frequently imposed by Nigerian authorities to pressure companies into settling outstanding regulatory disagreements or alleged tax liabilities.

The State Department's concerns extend to the treatment of international business travelers at Nigerian airports. Over the past year, local media investigations have revealed ongoing "shakedown" efforts by airport security officials, specifically targeting passengers perceived to be wealthy. Additionally, some foreign travelers entering Nigeria on business visas have encountered significant delays when attempting to depart the country. Immigration officials are reportedly scrutinizing the activities undertaken by these visitors to ascertain whether they have violated their visa conditions, as business visas typically permit meetings and related commercial engagements but do not authorize paid employment.

The cumulative effect of these reported incidents and warnings is a significant elevation of the risk profile for foreign businesses and their executives operating in or traveling to Nigeria. The US State Department's explicit guidance underscores that even routine business activities can lead to severe personal consequences, including arbitrary detention and travel restrictions, particularly when regulatory or financial disputes arise. This environment necessitates a proactive and thorough approach to risk management.

Lawyers and compliance officers advising foreign businesses operating in or traveling to Nigeria must immediately review and update risk assessments, particularly regarding regulatory investigations, tax disputes, and visa compliance, to mitigate the heightened risk of arbitrary detention and travel restrictions for executives, as highlighted by the US State Department and the Binance executive case.
