The United States is one of the most active countries in the field of international criminal prosecution. American prosecutors and agencies — the FBI, the DEA, and the Department of Justice — regularly secure the surrender of suspects from dozens of states around the world. Understanding the extradition mechanism is critically important for practicing lawyers and for individuals whose interests this legal phenomenon touches.
This article examines the key aspects of extradition from and to the United States: the legal framework, the role of international organizations including Interpol, and the connection between this instrument and financial crimes and sanctions regimes.
The Legal Basis for Extradition
Extradition is the formal legal procedure for transferring an accused or convicted individual from one state to another for the purpose of criminal prosecution or enforcement of a sentence. Unlike deportation, extradition is governed by specialized international treaties.
U.S. Extradition Treaties
The United States has concluded extradition treaties with approximately 100 states. Each such treaty establishes:
• the list of extraditable offenses, or the principle of “dual criminality” (the act must constitute a crime in both countries);
• the procedure for submitting a request and accompanying documents;
• grounds for refusal — political offenses, the risk of the death penalty, expiration of the statute of limitations;
• the rights of the requested individual to seek judicial review.
Where No Treaty Exists
Where no extradition treaty exists between the United States and a given state, transfer of an individual may be possible on the basis of reciprocity — though this is a rare and politically sensitive mechanism. In such cases, the United States frequently employs alternative instruments:
• issuance of an Interpol Red Notice;
• pressure through diplomatic channels;
• sanctions pressure on the financial system of the harboring state;
• “voluntary” travel by the individual to a third country followed by arrest there.
The Role of Interpol in International Fugitive Pursuit
Interpol (the International Criminal Police Organization) is the world’s largest intergovernmental police organization, with 195 member states. Its headquarters are located in Lyon, France. Interpol itself is not a police force, and its notices carry no binding legal force — yet in practice they exert considerable pressure.
The Interpol Notice System
Interpol uses eight types of color-coded notices. In the context of extradition, the most significant are:
• Red Notice — a request to member states to locate and provisionally detain an individual with a view to extradition. This is not an international arrest warrant; however, most states treat it as such in practice.
• Blue Notice — a request to collect information about an individual, their movements, and their activities.
• Yellow Notice — a request to assist in locating missing persons, including minors.
Red Notices and Human Rights
Experience has shown that Red Notices may be used by states for politically motivated prosecutions. For this reason, Interpol maintains a Commission for the Control of Interpol’s Files (CCF), which reviews complaints from individuals who consider notices to be unlawful. Between 2015 and 2023, the CCF removed hundreds of Red Notices upon applications from petitioners, including citizens of Russia, Kazakhstan, Ukraine, and a number of other states.
Extradition and Financial Crimes
Financial crimes — fraud, money laundering, tax evasion, and market manipulation — have constituted a significant share of U.S. extradition requests over the past two decades. U.S. financial investigations are characterized by particular aggressiveness: American law has an extraterritorial character, meaning that U.S. courts assert jurisdiction even where a crime was committed outside the country, provided it involved U.S. dollars, American banks, or correspondent accounts.
The Principle of Extraterritoriality
It is on this principle that the most high-profile criminal cases of recent years are based. If a foreign company conducted a transaction in U.S. dollars through an American correspondent bank, the Department of Justice considers itself to have jurisdiction. This enables American prosecutors to pursue individuals worldwide — regardless of their nationality or the location of the offense.
Typical Categories of Cases
Among the most common categories of financial cases for which the United States seeks extradition are:
1. Money laundering through U.S. financial institutions.
2. Tax evasion using offshore accounts (FATCA and FBAR violations).
3. Securities fraud and insider trading.
4. Violations of sanctions law — transactions with persons on the SDN list.
5. Cybercrime with financial consequences — ransomware and business email compromise (BEC) attacks.
In some cases, a traffic stop or accident investigation serves as the entry point to a large-scale federal financial case.
Sanctions as a Parallel Pressure Instrument
U.S. sanctions legislation — administered primarily by the Office of Foreign Assets Control (OFAC) — is closely intertwined with criminal prosecution. Inclusion of an individual or company on the SDN (Specially Designated Nationals) list effectively cuts them off from the global financial system, since most major banks worldwide apply U.S. sanctions voluntarily — out of fear of finding themselves under U.S. investigation.
The Interaction of Sanctions and Extradition
Sanctions frequently precede criminal prosecution and are used as a pressure tool: an individual placed on the SDN list loses the ability to operate normally and may be induced to cooperate with investigators. In parallel, an arrest warrant may be issued and an extradition request submitted through Interpol. This creates a multi-layered form of pressure — legal, financial, and reputational.
The Extradition Procedure: A Step-by-Step Outline
For a practical understanding, it is important to know exactly how an extradition procedure unfolds under U.S. law:
6. Investigation. A U.S. agency (FBI, DEA, SEC, IRS) conducts the investigation and refers the matter to a prosecutor.
7. Arrest warrant. A federal judge issues an arrest warrant on the basis of probable cause.
8. Interpol Red Notice. Where the suspect is abroad, the United States submits a request to Interpol for the issuance of a Red Notice.
9. Diplomatic request. The Department of Justice, through the State Department, submits a formal extradition request to the state where the suspect is located.
10. Arrest and hearings in the requested state. Local courts review the request, verify compliance with treaty requirements, and rule on extradition.
11. Appeals. The detained individual has the right to appeal the extradition decision through the highest judicial instances, which may take years.
12. Physical transfer. Once all appeals are exhausted, the individual is surrendered to U.S. agents and transported to the United States to stand trial.
Defenses Against Extradition: Legal Instruments
A number of legal grounds are invoked by defense counsel when challenging extradition:
• Dual criminality: if the act does not constitute a crime in the requested state, extradition is impermissible.
• Political offense: an exception for offenses of a political character. In practice, this is rarely applied given the broad interpretation of the concept.
• Risk of the death penalty: most European states refuse extradition unless the United States provides assurances that the death penalty will not be applied.
• Violation of the right to a fair trial: the argument that the U.S. investigation or judicial system will not provide adequate procedural guarantees.
• Expiration of the statute of limitations: if under the laws of the requested state the act is no longer prosecutable due to the passage of time, extradition may be refused.
Extradition remains a powerful and actively used instrument of American criminal justice. In combination with sanctions pressure and Interpol mechanisms, it creates an international enforcement system that effectively knows no geographic boundaries. The defining trends of recent years are the extraterritorial application of U.S. financial legislation, the use of sanctions as a pre-trial pressure tool, and active cooperation with partner states through Interpol. Understanding these mechanisms is critically important for lawyers practicing in the field of international criminal and financial law.
