What Is Extradition? Meaning, Process & Your Rights

In short: Extradition is the formal legal process by which one country surrenders a person to another country to face criminal charges or serve a sentence. It runs on treaties, requires a court to review the request, and can be challenged. If you or a loved one is named in an extradition request or an Interpol Red Notice, early legal advice is critical.

What does extradition mean?

Extradition means the formal, treaty-based transfer of a person from the country where they are located (the “requested” state) to the country that wants to prosecute or punish them (the “requesting” state). It is not the same as deportation or ordinary arrest: extradition is a government-to-government request, reviewed by a court, and governed by an international treaty and domestic law.

The word describes both the process and the outcome. A requesting country asks for a specific individual; the requested country’s authorities detain that person, a judge examines whether the legal conditions are met, and a government official makes the final surrender decision. In the United States, this framework is set out in Title 18 of the U.S. Code (18 U.S.C. §3181 and following) and carried out through the Department of Justice’s Office of International Affairs (OIA) and the Department of State.

Key fact: Extradition almost always requires a treaty. Under 18 U.S.C. §3181, the United States extradites to a foreign country only where an extradition treaty is in force, with narrow statutory exceptions.

Extradition matters because it removes a person from the protection of one legal system and delivers them to another, often for years of proceedings. That is why the process builds in judicial review and specific legal defenses — surrender is not automatic.

How does extradition work?

Extradition works as a sequence of defined stages that move from a foreign request to a final surrender decision. In broad terms, a treaty partner asks the United States (or vice versa) to hand over a named person, that person is arrested, a court tests the request against legal standards, and only then can the executive branch authorize surrender.

Here is the typical timeline for a request into the United States:

1. Request or complaint. The requesting country submits a formal extradition request through diplomatic channels. The DOJ’s OIA reviews it, and a federal prosecutor files a complaint in the U.S. district court where the person is found (18 U.S.C. §3184).
2. Provisional or formal arrest. In urgent cases the person may be arrested first, on a provisional arrest request, before the full paperwork arrives. Otherwise, arrest follows the formal complaint. Bail is limited — courts presume detention in extradition cases.
3. Extradition hearing. A federal judge or magistrate holds a hearing under §3184 to decide whether the offense is covered by the treaty and whether there is probable cause to believe the person committed it. This is not a full trial of guilt or innocence.
4. Certification. If the standards are met, the court certifies extraditability to the Secretary of State. If not, the person is discharged. A person cannot directly appeal certification but may seek habeas corpus review.
5. Surrender decision. The final call rests with the executive. The Secretary of State decides whether to surrender the person under 18 U.S.C. §3186, and may weigh humanitarian, human-rights, or foreign-policy factors before issuing a surrender warrant.

Outbound requests — the United States asking another country to return someone — follow that country’s own laws and treaty, but the stages are similar: request, arrest, court review, and an executive or ministerial decision.

Key fact: The extradition hearing tests probable cause and treaty coverage — not guilt. Under §3184, the question is whether the evidence would justify sending the case to trial, not whether the person is actually guilty.

If the request concerns surrender to the United States, our overview of the process and defenses for extradition to the United States explains what to expect and where a case can be contested.

International vs. interstate extradition

International and interstate extradition are two different systems that share a name. International extradition moves a person between sovereign countries under a treaty and federal law. Interstate extradition — often called rendition — moves a person between U.S. states under the Extradition Clause of the U.S. Constitution (Art. IV, §2) and the Uniform Criminal Extradition Act (UCEA), using a governor’s warrant rather than a treaty.

The legal tests, the paperwork, and the available defenses differ sharply between the two. A person facing transfer from Florida to Texas has very different rights from someone facing surrender from the United States to a foreign government. For a side-by-side comparison of the standards, timelines, and defenses, see our guide to how interstate and international extradition compare.

What is a provisional arrest?

A provisional arrest is an emergency detention of a person before the full extradition request has been received, used when there is a risk the person will flee. Under most treaties, the requesting country can ask for provisional arrest first and then submit the complete supporting documents within a set deadline — commonly 40 to 60 days, depending on the treaty.

This is one of the most time-sensitive moments in any extradition matter. A person can be taken into custody on little more than a foreign warrant and an Interpol alert, before any U.S. court has examined the merits. Bail is presumed against the detainee, so the practical effect is often weeks of detention while the paperwork catches up.

Key fact: Provisional arrest can happen before a formal extradition request exists. Because deadlines to challenge detention are short, contacting an extradition lawyer within the first days — not weeks — can shape the entire case.

Provisional arrest is frequently triggered by an Interpol Red Notice, which flags a wanted person to police worldwide. A Red Notice is not itself an arrest warrant, but it can prompt local detention and a provisional arrest request.

The role of treaties

Treaties are the legal foundation of extradition: they define which offenses are extraditable, what evidence is required, and what protections apply. Two doctrines carried by nearly every treaty are especially important — dual criminality and the rule of specialty.

• Dual criminality means the conduct must be a crime in both countries. If the alleged act is not an offense under U.S. law, it generally cannot support extradition, regardless of what the requesting country calls it.
• Rule of specialty means the person can be prosecuted only for the offenses for which they were surrendered — the requesting country cannot “bait and switch” and add unrelated charges after arrival.

Treaties also commonly exclude the political offense exception (surrender is barred for genuinely political offenses) and may require assurances against the death penalty or ill-treatment. The specific terms vary from one agreement to the next, which is why the exact treaty text matters so much. Our overview of U.S. bilateral extradition treaties explains which countries have agreements with the United States and how their terms differ.

Key fact: Under the rule of specialty, a surrendered person may generally be tried only for the offenses named in the extradition request — not for charges added afterward.

Can you fight extradition?

Yes — extradition can be contested, and doing so is a normal, legitimate part of the process. Surrender is never automatic: the requested person is entitled to a court hearing, and there are several recognized grounds to oppose it, from treaty and evidentiary challenges to human-rights arguments.

Common defenses include lack of dual criminality, insufficient probable cause, the political offense exception, expiry of the statute of limitations, procedural defects in the request, and risk of persecution, torture, or an unfair trial (Interpol Constitution Articles 2 and 3 bar abuse of the system for political or human-rights-violating ends). Where an Interpol Red Notice underlies the case, it can be challenged separately before the Commission for the Control of Interpol’s Files (CCF).

Because the strongest defenses depend on the facts, the treaty, and strict deadlines, they should be assessed by counsel immediately. Our guide to the recognized legal defenses against extradition sets out each ground in detail.

Frequently asked questions

What is the simple definition of extradition?

Extradition is the formal legal process by which one country surrenders a person to another country to face criminal charges or serve a sentence, under a treaty and with court review.

Is extradition the same as deportation?

No. Deportation is an immigration action removing a non-citizen from a country. Extradition is a treaty-based transfer to a specific country to face prosecution or punishment for named offenses, and it involves a court hearing.

Does extradition always require a treaty?

For the United States, almost always. Under 18 U.S.C. §3181, extradition generally requires an extradition treaty in force with the requesting country, subject to narrow statutory exceptions.

How long does the extradition process take?

It varies widely — from a few months to several years — depending on the treaty, whether the person contests surrender, appeals through habeas corpus, and how quickly the requesting country files its documents.

Can extradition be refused or challenged?

Yes. A person can raise defenses at the extradition hearing (for example, lack of dual criminality or insufficient evidence), seek habeas corpus review, and challenge an underlying Interpol Red Notice before the CCF.

What should I do if I learn of an extradition request or Red Notice?

Contact an extradition lawyer immediately. Deadlines are short, provisional arrest can happen before the full request arrives, and early legal action often shapes the outcome of the entire case.
