Extradition is the formal legal process one government uses to hand a person accused or convicted of a crime over to another government for prosecution or punishment. To understand what extradition means and how it works in practice, it helps to know that the United States runs two separate systems: international extradition, which depends on treaties and federal statute, and interstate extradition, which the U.S. Constitution makes effectively mandatory between states. The timelines, protections, and legal mechanics differ sharply between them.
The Two Tracks of Extradition
International extradition almost always rests on a treaty between the two countries involved. The treaty spells out which crimes are covered, what documentation the requesting country must supply, and what grounds exist for refusal. Without a treaty, there is no legal obligation to cooperate, though some countries will negotiate one-off arrangements.
Interstate extradition inside the United States is a constitutional matter. Article IV, Section 2 requires that a person charged with “Treason, Felony, or other Crime” who flees to another state must be returned on the demand of the state where the crime occurred.1Constitution Annotated. Overview of Extradition (Interstate Rendition) Clause The phrase “or other Crime” is broad on purpose. International extradition tends to cover only serious offenses; the constitutional mandate between states reaches all criminal charges.
How International Extradition Works
International cases move through several distinct phases, and the whole process is slower than most people expect.
The Request
Every formal extradition request travels through diplomatic channels. One country’s embassy delivers the request to the other country’s foreign affairs ministry, along with documents identifying the person, describing the charges, and showing that the offense is covered by the relevant treaty.2U.S. Department of State Foreign Affairs Manual (FAM). 7 FAM 1610 Introduction When a foreign government wants someone in the United States, the request goes to the State Department.
On the American side, the Department of Justice’s Office of International Affairs handles the paperwork. Every outgoing extradition request based on federal charges must be reviewed and approved by OIA before anything is sent, and incoming requests also flow through the office. Federal prosecutors are required to consult OIA before contacting any foreign official about extradition.3United States Department of Justice. 9-15.000 – International Extradition and Related Matters
Provisional Arrest
If prosecutors fear the person will flee before the full package can be assembled, they can request a provisional arrest. This asks the other country to detain the person immediately while the formal paperwork catches up.2U.S. Department of State Foreign Affairs Manual (FAM). 7 FAM 1610 Introduction Most treaties impose a deadline for following up with the formal request. Miss the deadline, and the person goes free.
The Judicial Hearing
Once a person is arrested in the United States on an extradition complaint, the case goes before a federal judge or magistrate judge. Under 18 U.S.C. § 3184, the judge holds a hearing to decide whether the evidence is sufficient to sustain the charge under the applicable treaty.4Office of the Law Revision Counsel. 18 U.S. Code Chapter 209 – Extradition This is not a trial on guilt or innocence. The judge checks whether a valid treaty exists, whether the person in custody is the person wanted, whether the charged offense is extraditable under the treaty, and whether the evidence establishes probable cause.2U.S. Department of State Foreign Affairs Manual (FAM). 7 FAM 1610 Introduction If those boxes are checked, the case is certified to the Secretary of State and the person is held in custody pending that decision.
The Secretary of State’s Decision
The final call belongs to the Secretary of State, who has statutory authority to order the person delivered to the requesting country’s agents.5Office of the Law Revision Counsel. 18 U.S. Code 3186 – Secretary of State to Surrender Fugitive The Secretary or a designated deputy reviews the record along with any humanitarian or diplomatic concerns before signing a surrender warrant.2U.S. Department of State Foreign Affairs Manual (FAM). 7 FAM 1610 Introduction This executive stage is where broader considerations like human rights and foreign relations can affect the outcome beyond the narrow legal questions a court addressed.
Transfer
Once the surrender warrant is signed, agents from the requesting country escort the person back to face charges. The requesting government pays the costs of apprehension, detention, and transport.6Office of the Law Revision Counsel. 18 U.S. Code 3195 – Payment of Fees and Costs
How Interstate Extradition Works
Between U.S. states, the process is faster and far more mechanical. The constitutional clause is not self-executing, so Congress passed the federal Extradition Act, codified at 18 U.S.C. § 3182, to supply the mechanics. The governor of the state seeking the fugitive sends a formal demand to the governor of the state holding the person, along with either an indictment or a sworn affidavit charging the crime. If the paperwork checks out, the receiving governor issues an arrest warrant and the person is held for pickup.4Office of the Law Revision Counsel. 18 U.S. Code Chapter 209 – Extradition
Most states have also adopted versions of the Uniform Criminal Extradition Act to fill in procedural details. The process was designed to be “summary and mandatory,” meaning governors have very limited discretion to refuse a valid demand.1Constitution Annotated. Overview of Extradition (Interstate Rendition) Clause
A person facing interstate extradition can waive the formal process entirely, giving up the right to a hearing and agreeing to be transported back voluntarily. Some defendants waive to signal cooperation. Others waive to avoid weeks of delay fighting a process that overwhelmingly favors the demanding state. Waiving extradition doesn’t affect the underlying criminal charges; it only skips the procedural fight over the transfer itself.
Two Principles That Shape Every Case
Two doctrines show up in nearly every extradition framework worldwide, both built to prevent abuse of the process.
The first is dual criminality. The conduct in question has to be a crime in both countries, the one requesting the person and the one holding them. If what you did is legal where you currently are, that country generally will not hand you over just because another government criminalizes it. Dual criminality gets checked early in every proceeding.2U.S. Department of State Foreign Affairs Manual (FAM). 7 FAM 1610 Introduction
The second is the rule of specialty. The receiving country can only prosecute or punish the person for the specific offenses listed in the extradition request, not pile on additional charges after arrival.2U.S. Department of State Foreign Affairs Manual (FAM). 7 FAM 1610 Introduction Federal prosecutors who want to bring charges beyond those in the original request must get clearance through OIA before proceeding.3United States Department of Justice. 9-15.000 – International Extradition and Related Matters
When Extradition Can Be Refused
International requests get denied more often than people realize. The grounds for refusal are built into the treaties themselves. These protections do not apply to interstate extradition.
Political Offense Exception
Nearly every extradition treaty allows the requested country to refuse surrender if the charged offense is political. Federal law reflects the same principle, barring the return of anyone charged with “an offense of a political nature.”4Office of the Law Revision Counsel. 18 U.S. Code Chapter 209 – Extradition Classic examples are treason, sedition, and espionage. The exception gets harder when violence is involved; countries draw the line differently on whether, say, a murder committed during a political uprising counts. Modern treaties increasingly carve acts of terrorism out of the exception.
Human Rights and the Death Penalty
A country can refuse extradition when there is a substantial risk the person would face torture, inhumane treatment, or a fundamentally unfair trial. The death penalty is a recurring friction point. Countries that have abolished capital punishment often refuse to extradite anyone to a country that might execute them, unless the requesting country provides binding assurances that the death penalty will not be sought or carried out. The United States runs into this regularly when requesting people from European nations.
Nationality
Many countries, especially those with civil law traditions, refuse to hand over their own citizens for trial abroad. Germany’s prohibition is written into its constitution. France’s is a legislative rule under the Code of Criminal Procedure. When these countries refuse, they often agree to prosecute the person domestically using evidence the requesting country provides. Russia and China also constitutionally prohibit extraditing their nationals. The United States has no blanket prohibition on extraditing its own citizens, but actual extradition of Americans to foreign countries remains uncommon.
No Treaty, Expired Limitations, No Dual Criminality
Extradition can also fail when the statute of limitations has expired in the requested country, or when the conduct is not criminal where the person currently is. The absence of a treaty is another practical barrier. Notable countries without a U.S. extradition treaty include Russia, China, the United Arab Emirates, Saudi Arabia, and Qatar.
What Rights the Person Has
People facing extradition are not without legal protections, though the options are narrower than in a regular criminal case. The most important point: an extradition hearing is not a trial. No court in the requested country decides whether you are guilty. The question is only whether the legal requirements for surrender have been met.
The primary tool for challenging extradition in the United States is a writ of habeas corpus. Through habeas review, a court examines whether the extradition itself is legally valid: does the treaty apply, does the crime qualify as extraditable, does the evidence meet the required threshold, and are there mandatory grounds for refusal.4Office of the Law Revision Counsel. 18 U.S. Code Chapter 209 – Extradition The court will not weigh whether you actually committed the offense.
Bail during international extradition is technically available but very hard to get. Under longstanding Supreme Court precedent, bail “should not ordinarily be granted in cases of foreign extradition” unless “special circumstances” exist.7Congress.gov. Bail: An Abridged Overview of Federal Criminal Law Courts treat flight risk as a near-presumption, for the obvious reason that the person is already in a different jurisdiction than the one that wants them.
How Long It Takes
International extradition is slow. According to the Department of Justice, cases “can take many months or even years to complete.”8United States Department of Justice. Frequently Asked Questions Regarding Extradition Once the U.S. submits a formal request to a foreign government, it loses control over the pace. Foreign courts set their own schedules, and executive review takes as long as it takes.
Interstate extradition moves much faster. Most cases resolve in a matter of weeks, particularly when the person waives the formal hearing.
Interpol Red Notices Are Not Arrest Warrants
A common misconception is that an Interpol red notice is an international arrest warrant. It is not. A red notice is a request to law enforcement agencies worldwide to locate and provisionally arrest a person pending extradition or similar legal action.9Interpol. View Red Notices It functions as an international “wanted” alert. The actual extradition still requires a formal request through diplomatic and legal channels, backed by a treaty. A red notice can help locate a fugitive, but it carries no independent authority to compel any country to surrender anyone.
