The extradition process is the formal mechanism by which one government surrenders a person to another jurisdiction to face criminal charges or serve a sentence, and in the United States it runs on two separate tracks: international extradition governed by treaties and federal statute, and interstate extradition rooted in the Constitution. Both tracks move through multiple layers of review before anyone is physically transferred, and both leave the accused with real opportunities to challenge or shorten the process.
How International Extradition Works
The United States generally will not surrender a person to a foreign government unless a formal extradition treaty is in place. Federal law ties the entire framework to the existence of such an agreement: the statutory provisions authorizing surrender “shall continue in force only during the existence of any treaty of extradition with such foreign government.”1Office of the Law Revision Counsel. 18 USC 3181 – Scope and Limitation of Chapter The U.S. maintains bilateral treaties with well over 100 countries, each spelling out which offenses qualify, what documentation requests must include, and what protections the accused retains.
Locating and Provisionally Arresting the Fugitive
Before a formal request is assembled, the requesting country usually needs the person located and detained. Interpol Red Notices do that work. A Red Notice is a request circulated to law enforcement worldwide asking them to find and provisionally arrest a person pending extradition. It is not an international arrest warrant; each country decides for itself what legal weight to give it.2Interpol. About Red Notices The provisional arrest buys time for the requesting country to assemble its formal package, which can take months.
Assembling the Formal Request
The requesting government must compile a detailed set of documents: photographs, fingerprints, and physical descriptions to identify the fugitive; a precise description of the alleged crime, applicable statutes, and potential penalties; and a certified copy of the arrest warrant from the domestic court. The formal request is transmitted by diplomatic note and must be translated into the language of the country where the fugitive is located.3U.S. Department of State Foreign Affairs Manual. 7 FAM 1610 – Introduction The evidence must be strong enough to justify arrest as if the crime had occurred locally. A U.S. judge reviewing an incoming request applies a probable cause standard.4Office of the Law Revision Counsel. 18 USC 3184 – Fugitives From Foreign Country to United States
The Judicial Hearing
Once the fugitive is arrested, the case goes before a federal district judge or magistrate judge for an extraditability hearing.3U.S. Department of State Foreign Affairs Manual. 7 FAM 1610 – Introduction This is not a trial on guilt or innocence. The judge checks whether the treaty covers the offense, whether the evidence meets probable cause, whether dual criminality is satisfied, and whether the person in custody is the individual named in the request. If the requirements are met, the judge certifies the case to the Secretary of State and orders the person held pending a final decision.4Office of the Law Revision Counsel. 18 USC 3184 – Fugitives From Foreign Country to United States
The Executive Decision and Transfer
A judicial finding of extraditability does not end the process. The final decision to surrender belongs to the Secretary of State or a designee, who can weigh humanitarian and diplomatic factors beyond what the judge examined.3U.S. Department of State Foreign Affairs Manual. 7 FAM 1610 – Introduction Once a surrender warrant is signed, the Secretary authorizes delivery of the fugitive to agents of the requesting country.5Office of the Law Revision Counsel. 18 USC 3186 – Secretary of State to Surrender Fugitive The U.S. Marshals Service handles the logistics, coordinating country clearance, security, and travel with the Department of Justice, the State Department, and U.S. embassies.6U.S. Marshals Service.

How Interstate Extradition Works
Returning a fugitive from one state to another is a constitutional obligation. Article IV, Section 2 provides that a person charged with a crime who flees to another state “shall on Demand of the executive Authority of the State from which he fled, be delivered up, to be removed to the State having Jurisdiction of the Crime.”7Congress.gov. Article IV Section 2 Clause 2 Congress reinforced this duty in 18 U.S.C. § 3182, which requires a state’s executive authority to arrest and deliver a fugitive when the demanding state produces a copy of the indictment or a sworn complaint certified by its governor. If the demanding state’s agent does not pick up the fugitive within 30 days of arrest, the person can be released.8Office of the Law Revision Counsel. 18 USC 3182 – Fugitives From State or Territory to State, District, or Territory
Nearly every state has adopted the Uniform Criminal Extradition Act, which fills in the procedural details. The process runs between the two governors. The demanding state’s governor sends a formal written request with charging documents and a prosecutor’s affidavit describing the crime and confirming the accused was present in the state and later fled. The receiving state’s governor reviews the request, may direct the attorney general to investigate, and if satisfied issues a governor’s warrant authorizing arrest and transfer.
Once a governor’s warrant is issued, existing bail is typically revoked and the fugitive is held in custody. The accused can challenge the warrant through habeas corpus, but the court’s review is narrow: whether the extradition documents are facially valid, and whether the person held is actually the individual named in the warrant. Courts do not evaluate the merits of the underlying charge.
Grounds That Can Block Extradition
Extradition is not automatic even when a treaty exists. Several categories of objection can stop a request.
Dual Criminality
Most treaties require that the alleged conduct be a crime in both countries. This prevents a government from surrendering someone for behavior that is perfectly legal on its own soil.3U.S. Department of State Foreign Affairs Manual. 7 FAM 1610 – Introduction Courts applying the standard focus on the underlying conduct, not whether both countries have identically named statutes. The question is whether the acts described would be punishable in both places.9United Nations Office on Drugs and Crime. Organized Crime Module 11 Key Issues – Extradition
Political Offense Exception
Nearly every treaty includes a clause allowing refusal when the offense is political in nature. Extradition is meant to enforce ordinary criminal law, not to help one government silence political opposition in another. U.S. law reflects this principle directly, requiring that charged offenses “are not of a political nature” before surrender can proceed outside a treaty.1Office of the Law Revision Counsel. 18 USC 3181 – Scope and Limitation of Chapter Drawing the line between a political offense and an ordinary crime committed with political motivation remains one of the hardest judgment calls in this area of law.
Death Penalty Concerns
Many countries will not surrender a person who faces execution. Countries across Europe, Canada, Mexico, and elsewhere have refused extradition outright or conditioned surrender on binding assurances that the death penalty will not be sought or imposed. When U.S. prosecutors want a fugitive badly enough, taking the death penalty off the table has become routine in capital cases involving international fugitives.
Nationality of the Accused
Many countries refuse to extradite their own citizens, or will do so only under narrow circumstances. Civil law jurisdictions in Europe and Latin America are especially likely to invoke this protection. The typical alternative is for the home country to prosecute the person domestically for the alleged offense.
Statute of Limitations
If the time to prosecute the underlying crime has expired under either country’s law, extradition can be blocked. Many treaties include lapse-of-time provisions that bar surrender when prosecution would be time-barred in either jurisdiction. This defense tends to matter most in older cases where a fugitive has lived abroad for years.
Fighting or Shortening Extradition
A person facing extradition is not without recourse. The primary tool for fighting surrender is a petition for habeas corpus. After a judge certifies extraditability, the accused can file a habeas petition arguing the detention is unlawful. Courts examine whether the extradition judge had jurisdiction, whether the offense falls within the treaty, whether the documents are facially valid, and whether the person held is the right individual. Courts will not relitigate probable cause or weigh evidence as if conducting a trial.
Federal law also imposes a time limit on the requesting country. Under 18 U.S.C. § 3188, if the fugitive is not physically removed from the United States within two calendar months after being committed for surrender, a judge can order release from custody unless the government shows sufficient cause for the delay.10Office of the Law Revision Counsel. 18 USC 3188 – Time of Commitment Pending Extradition The provision prevents someone from sitting in jail indefinitely while foreign bureaucracies process paperwork.
The most practical option for many people facing interstate extradition is to waive the process. By signing a waiver before a judge, a defendant agrees to return voluntarily to the charging state. The judge must confirm the waiver is knowing and voluntary, and the waiver cannot be used as evidence of guilt. For someone facing minor charges who would rather resolve the case than spend weeks in a holding facility waiting on a governor’s warrant, waiving extradition is often the fastest path to getting before a judge who can actually address the underlying charge.
The Rule of Specialty
One protection follows the person across the border. Under the rule of specialty, once a person is surrendered, the receiving country can only prosecute for the specific offenses listed in the extradition request. The requesting government cannot tack on additional charges, impose punishment for prior offenses not mentioned, or hand the person off to a third country without the surrendering country’s consent.9United Nations Office on Drugs and Crime. Organized Crime Module 11 Key Issues – Extradition The rule exists because without it, countries would be reluctant to cooperate at all. A government that surrenders someone for fraud does not want to learn that person was later prosecuted for political dissent.
