Interstate vs. International Extradition: Differences

By Melisa Kurter — Senior Associate; Interpol & extradition practice

In short: Interstate extradition moves a person between two US states under the Extradition Clause (U.S. Const. Art. IV, §2) and the Uniform Criminal Extradition Act, using a governor’s warrant. International extradition moves a person between two countries under a treaty and, for the US, under 18 U.S.C. §3184. They are entirely different legal processes with different rules, defenses, and stakes. If your matter crosses a national border, speak with an extradition lawyer — +357 96 447475.

Interstate vs. international extradition at a glance

The core difference is scope: interstate extradition transfers a person between two US states and is governed by the US Constitution and a uniform state statute, while international extradition transfers a person between two sovereign nations and is governed by a bilateral treaty and federal law. The two share a name but almost nothing else — the legal basis, the deciding authority, the available defenses, and the consequences all differ.

Feature	Interstate extradition	International extradition
Between	Two US states	Two countries
Legal basis	U.S. Const. Art. IV, §2 (Extradition Clause); Uniform Criminal Extradition Act (UCEA)	Bilateral treaty; 18 U.S.C. §3181–3196
Key document	Governor’s warrant (rendition warrant)	Formal extradition request via diplomatic channels
Deciding authority	Governor of the asylum state	Federal judge (§3184) + US Secretary of State (§3186)
Typical defenses	Identity; whether a crime was charged; whether you are a “fugitive”; document defects	Dual criminality; rule of specialty; political offense exception; treaty scope; human-rights grounds
Court review	Habeas corpus (limited)	Extradition hearing + habeas corpus review
Timeframe	Usually weeks	Often months to years
Discretion	Largely mandatory once requirements are met	Treaty-bound but with executive discretion at surrender

If your case involves crossing a US state line only, the sections below explain the process and your options. If it involves another country — or the United States seeking someone from abroad — you are in international extradition territory, where the stakes and the defenses are far greater.

What is interstate extradition?

Interstate extradition is the process of surrendering a person from one US state (the “asylum state”) to another (the “demanding state”) to face charges or serve a sentence. Its foundation is the Extradition Clause of the US Constitution (Art. IV, §2), which requires states to return fugitives on demand, implemented in nearly every state through the Uniform Criminal Extradition Act (UCEA).

Because the Constitution makes rendition between states largely mandatory, the asylum state has little discretion once the paperwork is in order. The demanding state’s governor requests surrender; the asylum state’s governor issues a governor’s warrant authorizing arrest and transfer. The process is administrative and generally fast, and it does not involve treaties, dual criminality, or the political offense exception — doctrines that belong to the international context.

Key fact: In interstate extradition the receiving state need only show that the person was charged with a crime and is a fugitive. The asylum state does not re-examine guilt, innocence, or the strength of the evidence.

A person facing interstate rendition can still challenge it, but the grounds are narrow: mistaken identity, whether they were actually in the demanding state when the offense occurred, whether the documents are in order, and whether the person is genuinely charged. These challenges are usually raised through a habeas corpus petition in the asylum state.

What is international extradition?

International extradition is the treaty-based process by which one country surrenders a person to another to face prosecution or serve a sentence. When the United States is involved, it runs on a bilateral treaty plus federal law: a formal request through diplomatic channels, a complaint and hearing under 18 U.S.C. §3184, and a final surrender decision by the Secretary of State under §3186. Our full explanation of how extradition works walks through each stage.

Unlike interstate rendition, international extradition is layered with protective doctrines. Dual criminality requires that the conduct be a crime in both countries; the rule of specialty limits prosecution to the offenses for which surrender was granted; and the political offense exception bars extradition for certain political conduct. A federal judge assesses probable cause and treaty scope, and the executive retains discretion at the final step — so both judicial and diplomatic defenses matter.

The stakes are also higher. International cases can involve a provisional arrest before any formal request arrives, an Interpol Red Notice restricting travel and banking, and detention in a foreign jurisdiction. If the United States is seeking a person abroad, see how we defend against surrender to US authorities; if a foreign state is seeking someone inside the US, see defending a §3184 proceeding in the United States.

Governor’s warrant explained

A governor’s warrant is the document that authorizes an interstate transfer. It is issued by the governor of the asylum state after the demanding state’s governor submits a formal requisition — typically an indictment or affidavit, a copy of the charging document, and certification that the person is a fugitive from that state. Once issued, it functions as the legal authority to arrest and hold the person for surrender.

Before a governor’s warrant arrives, a person may be held on a fugitive warrant or arrested on an out-of-state charge, often for a limited statutory period while the demanding state prepares its requisition. When the governor’s warrant issues, the person’s remedy is a habeas corpus hearing — but the court’s review is narrow. It asks whether the extradition documents are facially valid, whether the person named is the person held, whether they are charged with a crime, and whether they are a fugitive. It does not retry the underlying case.

Waiver of extradition in each context

You can waive extradition in both contexts, but the meaning and the risk are different. Waiving means giving up the formal process and agreeing to be transferred voluntarily — in interstate cases this simply speeds an almost-certain rendition, while in international cases it surrenders powerful treaty defenses that could otherwise stop the transfer entirely.

In an interstate matter, waiver is often a practical choice: because rendition is largely mandatory, contesting it rarely changes the result and can prolong detention. In an international matter, waiver is a decision that should never be made without counsel — you may be giving up dual-criminality, specialty, political-offense, and human-rights arguments that are the whole basis of a defense. Read our detailed guide to waiving or contesting extradition before signing anything.

Key fact: A waiver in an international case can extinguish defenses that do not exist at all in the interstate context — which is exactly why the same word carries very different consequences.

Which one applies to you?

Ask one question: does the transfer cross a US state line, or a national border? If someone is wanted in another US state, you are in interstate extradition — a mostly administrative process where an experienced criminal lawyer in the relevant states can advise on the governor’s warrant and any habeas petition. If another country is involved, or the United States is reaching across a border, you are in international extradition.

International cases are where treaty defenses, Interpol Red Notices, and the risk of foreign detention come into play — and where early, specialized legal action matters most. That is our focus. If your matter crosses a national border in either direction, do not wait for a formal request to arrive.

FAQ

Is interstate extradition the same as international extradition?

No. Interstate extradition moves a person between two US states under the Constitution and the Uniform Criminal Extradition Act, using a governor’s warrant. International extradition moves a person between two countries under a treaty and, in the US, under 18 U.S.C. §3184. The legal rules and defenses are completely different.

What is a governor’s warrant?

A governor’s warrant is the document the governor of the asylum state issues to authorize the arrest and transfer of a person wanted in another US state. It follows a formal requisition from the demanding state’s governor and is the legal basis for interstate rendition.

Can I fight interstate extradition?

You can, but the grounds are narrow. A habeas corpus court reviews only whether the documents are valid, whether you are the person named, whether you are charged with a crime, and whether you are a fugitive. It does not examine guilt or the strength of the evidence.

Which process has stronger defenses?

International extradition offers far more defenses — dual criminality, the rule of specialty, the political offense exception, treaty-scope challenges, and human-rights arguments. Interstate rendition is largely mandatory under the Constitution, so its defenses are limited.

Does an Interpol Red Notice relate to interstate extradition?

No. Interpol operates only between countries, so a Red Notice is relevant to international extradition, not to transfers between US states. Interstate matters are handled entirely within the US legal system.

Should I waive extradition?

It depends on the context and should never be decided without counsel. In interstate cases waiver may simply speed an almost-certain transfer, but in international cases it can surrender treaty defenses that might otherwise stop the extradition. Get legal advice first.
