A foreign warrant in the US has no independent legal force. A warrant issued by a court in another country cannot be executed by American police or federal agents on its own authority. Before anyone can be arrested and sent abroad, a foreign government has to work through international alert systems, a bilateral extradition treaty, a federal court hearing, and a final decision by the Secretary of State. The process often takes months or years, and the person being sought has real chances to fight surrender along the way.
How US Authorities Learn a Foreign Country Wants You
Most of the time, it starts with Interpol. When a foreign government wants someone located and arrested abroad, it can ask Interpol to publish a Red Notice. Interpol describes a Red Notice as “a request to law enforcement worldwide to locate and provisionally arrest a person pending extradition, surrender, or similar legal action.”1Interpol. About Red Notices Each one is backed by an arrest warrant or court order from the requesting country.
A Red Notice is not an international arrest warrant, and Interpol says so directly.1Interpol. About Red Notices It gives no American officer the power to arrest. The FBI and the Department of Homeland Security treat Red Notices as intelligence flags, especially at borders and during immigration processing. If someone matching a Red Notice shows up, US authorities know a foreign government wants that person, but that knowledge alone is not a legal basis for custody.
For an actual arrest to happen on US soil, federal authorities have to go through domestic legal channels: a sworn complaint before a federal judge or magistrate, with enough evidence to meet US standards. The Red Notice is the trigger for attention, not the authority to act.
You Usually Need a Treaty
Extradition is the formal legal mechanism for physically surrendering a person to another country, and it almost always depends on a treaty. Federal law states that the extradition provisions of Chapter 209 of Title 18 “shall continue in force only during the existence of any treaty of extradition with such foreign government.”2Office of the Law Revision Counsel. 18 US Code 3181 – Scope and Limitation of Chapter If there is no treaty with the requesting country, federal courts generally have no jurisdiction to hold extradition proceedings.
One narrow exception exists. Even without a treaty, the Attorney General may authorize surrender of a person who is not a US citizen, national, or permanent resident if that person committed a crime of violence against a US national abroad and the offense is not political.2Office of the Law Revision Counsel. 18 US Code 3181 – Scope and Limitation of Chapter Outside that scenario, no treaty means no extradition.
The US has bilateral extradition treaties with over 100 countries. Terms vary. The specific treaty between the US and the requesting country decides which offenses qualify, what evidence has to be submitted, and what protections apply.
What the Extradition Process Actually Looks Like
Once a foreign government decides to pursue extradition rather than just share information, several steps have to happen before anyone is handed over.
The Request and DOJ Review
The foreign government submits a formal extradition request to the US Department of State. The State Department checks whether the paperwork meets the procedural requirements of the applicable treaty: the foreign arrest warrant, a description of the charges, and a summary of the evidence.
If the submission is in order, State works with the Department of Justice’s Office of International Affairs to evaluate legal sufficiency.3U.S. Department of State. Department of State’s Role in the Extradition Process The OIA looks at whether the facts could establish probable cause under US constitutional standards and whether the offense falls within the treaty. Legally deficient requests do not reach court.
Provisional Arrest
When authorities think the person might flee before the full package arrives, DOJ can seek a provisional arrest warrant. Under 18 U.S.C. § 3184, a federal judge or magistrate may issue a warrant on a sworn complaint charging a person found within US jurisdiction with a treaty-covered crime.4Office of the Law Revision Counsel. 18 USC 3184 – Fugitives from Foreign Country to United States US Marshals take the person into custody.
Provisional arrest is not open-ended. If the complete extradition documents do not arrive within the window set by the treaty, commonly 40 to 60 days, the person must be released.
The Extradition Hearing
Once the full request is in, a federal magistrate judge or district court judge holds an extradition hearing. This is not a trial, and the judge does not decide guilt. The judge is answering three narrower questions: whether the treaty covers the alleged crime, whether the person in custody is the person named in the foreign warrant, and whether the evidence is sufficient to sustain the charge.
The statute directs that if the judge “deems the evidence sufficient to sustain the charge under the provisions of the proper treaty or convention,” the case is certified to the Secretary of State.4Office of the Law Revision Counsel. 18 USC 3184 – Fugitives from Foreign Country to United States The standard is probable cause, the same bar used for domestic arrest warrants.
If the judge denies certification, the case is over. The government cannot appeal that denial. The person is released, and the requesting country would have to start fresh.
The Secretary of State’s Decision
A judge’s certification is a recommendation, not a final order. The actual surrender decision belongs to the Secretary of State. The statute says the Secretary “may order the person committed under sections 3184 or 3185 of this title to be delivered to any authorized agent of such foreign government.”5GovInfo. 18 USC 3186 – Secretary of State to Surrender Fugitive The word “may” matters. The Secretary can refuse even after a court has found the person extraditable, sometimes on humanitarian grounds like torture concerns or inhumane prison conditions, sometimes for diplomatic reasons unrelated to the legal merits.
Detention, Bail, and How Long All This Takes
People facing extradition usually spend significant time in federal custody. Bail is unusually hard to get. Federal courts follow a Supreme Court rule that “bail should not ordinarily be granted in cases of foreign extradition” except under “special circumstances.”6Congress.gov. Bail: An Abridged Overview of Federal Criminal Law There is no fixed definition of what qualifies, but courts reserve it for truly extraordinary situations, and the person still has to show they will not flee and will not pose a danger.
There is one backstop against indefinite detention. Under 18 U.S.C. § 3188, if the person is not surrendered and “conveyed out of the United States within two calendar months after such commitment,” a judge may order release unless the government shows sufficient cause for the delay.7Office of the Law Revision Counsel. 18 USC 3188 – Time of Commitment Pending Extradition The two-month clock starts after the certification order, not after the initial arrest.
The overall timeline is open-ended. DOJ has acknowledged that extradition “can take many months or even years to complete,” and that once a request reaches a foreign government, “the United States does not control the pace of the proceedings.”8Department of Justice. Frequently Asked Questions Regarding Extradition The same unpredictability runs the other way when the US is the country being asked.
How to Fight Extradition
A person facing extradition has two main procedural tools. The first is the extradition hearing itself, where counsel can argue that the treaty requirements are not met, that the evidence falls short, or that a legal defense bars surrender. The second is a petition for a writ of habeas corpus under 28 U.S.C. § 2241, filed after certification. Habeas is the main route to appellate-level review, because the certification order itself is not directly appealable by either side. It lets a federal court examine whether the magistrate correctly applied the law, whether the treaty’s requirements were really satisfied, and whether constitutional protections were violated.
Getting a Lawyer
Extradition cases sit in an unusual legal space. They are not criminal prosecutions, so the automatic right to appointed counsel that applies in federal criminal cases does not strictly extend to extradition. Federal courts do have discretion to appoint counsel for people held for international extradition who cannot afford one.9USCourts.gov. Guide to Judiciary Policy – Appointment and Payment of Counsel In practice, many do, given the complexity of the proceedings. Anyone facing a potential extradition should get representation as early as possible, either privately or by asking the court for appointment.
Defenses That Can Block Surrender
Dual Criminality
This is probably the most common defense. The conduct underlying the foreign charges has to be criminal in the US as well. The State Department describes dual criminality as “a threshold requirement in extradition, that the conduct for which extradition is sought must be a crime under the laws of both the requesting and the requested countries.” The focus is on the behavior, not on whether both countries use the same label. If the conduct is lawful in the US, extradition must be denied. Most treaties also require that the offense carry more than one year of imprisonment in both countries.10U.S. Department of State. 7 FAM 1600 The Consular Role in International Extradition
The Political Offense Exception
Nearly all extradition treaties bar surrender for political offenses. The point is to prevent the US from helping another government punish political dissent. Modern treaties have narrowed this considerably: most now expressly exclude terrorism, assassination, and hostage-taking from counting as political, even where the actor claims a political motive. The exception still has force for nonviolent political activity, but courts apply it carefully.
Insufficient Evidence
The foreign submission has to meet the US probable cause standard. A thin, disorganized, or poorly supported package means the judge must deny certification. The quality of the requesting country’s filing often decides the case.
Risk of Torture
The UN Convention Against Torture, which the US has ratified, says no country shall “expel, return or extradite a person to another State where there are substantial grounds for believing that he would be in danger of being subjected to torture.”11United Nations. Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment That obligation applies even when the technical treaty requirements are met. In practice, this concern often influences the Secretary of State’s decision rather than the judicial hearing, since the Secretary has wider discretion to weigh human rights conditions.
The Rule of Specialty
Specialty protects the person after surrender. The requesting country can prosecute only for the offenses listed in the extradition request. It cannot use extradition to get custody and then stack unrelated pre-surrender charges.12United Nations Office on Drugs and Crime. Extradition Adding charges requires going back to the US for a formal waiver.
When the Foreign Government Only Wants Evidence
Not every foreign warrant leads to an extradition request. Sometimes the foreign government wants records or testimony, not the person. Mutual Legal Assistance Treaties handle that. These bilateral agreements let foreign governments ask the US for help gathering evidence for foreign criminal investigations and prosecutions, processed through DOJ’s Office of International Affairs.
Typical assistance includes compelling witness testimony, producing bank records, and freezing or seizing assets. A federal district court can order a person within its jurisdiction to testify or produce documents “for use in a proceeding in a foreign or international tribunal, including criminal investigations conducted before formal accusation.”13Office of the Law Revision Counsel. 28 US Code 1782 – Assistance to Foreign and International Tribunals and to Litigants Before Such Tribunals MLATs never authorize arrest or surrender. If the foreign government only needs evidence, this route sidesteps extradition entirely.
Deportation as a Workaround
When formal extradition is not available, the government sometimes uses immigration enforcement instead. The State Department’s Foreign Affairs Manual acknowledges that extradition “is not always feasible” and that the US “may seek the person’s return by way of deportation or expulsion.”14U.S. Department of State. 7 FAM 1640 Other Extradition Matters That can happen when the crime is not extraditable under the treaty, when no treaty exists, or when the person is already in removal proceedings.
The practical consequence is substantial. People “being returned to the United States by deportation or expulsion do not fall under extradition treaty requirements.”14U.S. Department of State. 7 FAM 1640 Other Extradition Matters Dual criminality, the political offense exception, and the rule of specialty do not apply. A non-citizen in the US who faces both a foreign warrant and a potential immigration violation can end up with far fewer legal protections than someone the foreign government goes after through formal extradition. That is the risk worth understanding first and acting on early, with a lawyer.
