The US Extradition Process: Steps, Hearing & Timeline
By Hanna Sianko — Associate Partner, LLM (LSE); practice in the UK and the United States
In short: The US extradition process runs through five stages — a formal request or provisional arrest, a federal complaint and arrest, an extradition hearing under 18 U.S.C. §3184, a surrender decision by the Secretary of State under §3186, and physical transfer. It is not a full criminal trial, and the only court review after certification is habeas corpus, not a direct appeal. Speak with an extradition lawyer confidentially: +357 96 447475.
Extradition is a structured legal process, not a single event. Whether the US is asking a foreign country to hand someone over, or a foreign state is asking the US to surrender a person on American soil, the case moves through fixed stages defined by 18 U.S.C. §3181–§3196 and split between the courts and the executive branch. This guide walks through each step, explains what the extradition hearing does and does not decide, and shows where a defense lawyer can intervene.
How does the US extradition process work?
The US extradition process works in five ordered stages: a requesting state submits a formal extradition request (or seeks a provisional arrest for urgent cases), a federal prosecutor files a complaint and the person is arrested, a federal judge holds an extradition hearing under 18 U.S.C. §3184, the Secretary of State makes the final surrender decision under §3186, and the person is physically transferred. Courts decide extraditability; the executive decides surrender.
Every international extradition case follows the same skeleton, whichever direction the request travels:
- Formal request or provisional arrest. The requesting government transmits an extradition request through diplomatic channels under the applicable treaty. If the matter is urgent, it can first seek a provisional arrest under the treaty and §3184 — detaining the person before the complete documentation arrives.
- Review and complaint. The Department of Justice Office of International Affairs (OIA) screens incoming requests for treaty and statutory sufficiency; a federal prosecutor then files a complaint in the district where the person is found, and a warrant issues.
- Arrest and initial custody. The person is taken into custody. Because there is a presumption against release in extradition matters, bail is the exception, not the rule (see below).
- The §3184 extradition hearing. A federal judge or magistrate decides whether a valid treaty applies, whether the conduct satisfies dual criminality, and whether there is probable cause. If so, the judge certifies extraditability to the Secretary of State.
- Surrender and transfer. The Secretary of State decides under §3186 whether to surrender the person and, if so, signs the surrender warrant; the person is then physically transferred to the requesting state’s agents.
Key fact: A provisional arrest can occur before the requesting state has filed its complete extradition package — which is why the first 48–72 hours often shape the entire case.

The extradition hearing explained
The extradition hearing under 18 U.S.C. §3184 is a limited judicial proceeding, not a full criminal trial. The judge answers three narrow questions: whether a valid extradition treaty applies, whether the offense satisfies dual criminality (a crime in both countries), and whether there is probable cause to believe the person committed the charged conduct. Guilt or innocence is never decided here — that belongs to the requesting state’s courts.
Because the hearing is so contained, people are often startled by what it excludes. Understanding those boundaries is the heart of the defense.
| Feature | Extradition hearing (§3184) | Ordinary criminal trial |
|---|---|---|
| Question decided | Extraditability (treaty, dual criminality, probable cause) | Guilt or innocence |
| Jury | No | Yes |
| Standard of proof | Probable cause | Beyond a reasonable doubt |
| Defense evidence | Limited — may “explain,” not “contradict” | Full defense permitted |
| Outcome | Certification or discharge | Verdict |
The evidentiary limit matters most: in most circuits the person may offer evidence that explains the requesting state’s case but not evidence that merely contradicts it. Winning here usually means attacking whether the treaty applies, whether the conduct is actually a crime under US law, and whether the materials establish probable cause — the legal grounds that defeat extradition are argued within these limits.
Is bail available in extradition cases?
Bail is available in extradition cases but is difficult to obtain. Unlike ordinary federal criminal matters, extradition carries a presumption against release, and a person is granted extradition bail only on a showing of “special circumstances” together with proof that they are not a flight risk. This standard is stricter than the ordinary bail analysis, and courts apply it cautiously to honor the US treaty obligation to produce the person.
“Special circumstances” is not a fixed checklist, but arguments courts have entertained include serious health conditions, unusual delay, a high probability of success at the hearing, or the need to prepare a complex challenge. Because the presumption starts against you, an early, well-documented bail application is one of the most valuable steps counsel can take.
Key fact: Extradition bail requires “special circumstances,” a materially higher bar than ordinary federal bail — release is the exception, not the default.
Habeas corpus review: the only path
There is no direct appeal from a §3184 certification of extraditability. Because a magistrate’s certification is not a final judgment in the ordinary sense, the only way to challenge it in the courts is to file a petition for a writ of habeas corpus in federal district court — and that ruling can then be appealed through the normal appellate channels.
Habeas review is narrow. A court generally examines only whether the judge had jurisdiction, whether the offense falls within the treaty, and whether any evidence supported the probable-cause finding — it does not re-weigh the evidence the way an appellate court reviews a trial. That limited scope is exactly why the record must be built correctly at the hearing itself: arguments not preserved at the §3184 stage are very hard to raise afterward.
What happens after an extradition order?
After a judge certifies extraditability, the decision passes to the Secretary of State, who makes the final surrender decision under 18 U.S.C. §3186. The Secretary may decline to surrender — even after the court has found the legal requirements met — for humanitarian, foreign-policy, or human-rights reasons. This executive stage is a genuine, separate opportunity for advocacy, not a rubber stamp.
If surrender is authorized, the Secretary signs a surrender warrant, the requesting state’s agents take custody, and the person is physically transferred, typically within the time window the treaty allows. Two protections continue to matter after the order:
- Rule of specialty. The surrendered person may generally be prosecuted only for the offenses for which extradition was granted — not for other or later-added charges. Counsel insists on this and monitors compliance after transfer.
- Conditions and assurances. At the executive stage, and sometimes as a condition of surrender, the US may seek diplomatic assurances on treatment, detention conditions, or the exclusion of the death penalty.
How long does the US extradition process take?
There is no fixed timetable for US extradition; total duration varies widely with the facts of each case. The length is driven by how quickly the requesting state files complete documentation, whether the person is detained or released, how contested the §3184 hearing is, whether a habeas corpus petition (and appeal) is pursued, and how long the Secretary of State takes to decide surrender.
Contested cases with a habeas challenge run longer than uncontested ones, and a voluntary waiver of extradition can shorten the process dramatically by skipping the hearing. Because timing turns on these variables, no responsible lawyer should quote an “average” — but each stage is also a chance to slow an unlawful request.
How a lawyer intervenes at each stage
A lawyer can intervene at every stage, and the earliest interventions are usually the most decisive. Counsel tests the treaty and the request the moment a provisional arrest occurs, opposes detention with a special-circumstances bail motion, litigates the §3184 hearing on treaty applicability, dual criminality and probable cause, files habeas corpus review, and presses humanitarian and specialty arguments before the Secretary of State.
The direction of the case shapes the strategy. Where a foreign state seeks a person on US soil, the defense is built around contesting surrender from the United States; where the US is the requesting state, the fight runs through defending against extradition to the United States. Both begin from the same foundation set out in our overview of what extradition is and how it operates.

FAQ
How does extradition work in the United States?
Extradition works through five stages: a formal request or provisional arrest, a federal complaint and arrest, an extradition hearing under 18 U.S.C. §3184, a final surrender decision by the Secretary of State under §3186, and physical transfer. Courts decide whether a person is extraditable; the executive branch decides whether to surrender them.
What happens at an extradition hearing?
At a §3184 hearing a federal judge decides only three things: whether a valid treaty applies, whether the conduct is a crime in both countries (dual criminality), and whether there is probable cause. It is not a trial, there is no jury, and guilt or innocence is decided later in the requesting country.
Can you get bail in an extradition case?
Bail is possible but difficult. US courts apply a presumption against release in extradition matters, and bail is granted only where the person shows “special circumstances” and that they are not a flight risk — a materially higher bar than in ordinary federal cases.
Is there an appeal after an extradition order?
There is no direct appeal from a certification of extraditability. The only court review is a petition for a writ of habeas corpus filed in federal district court, which can then be appealed through the normal federal appellate process.
What happens after an extradition order is signed?
After the Secretary of State signs the surrender warrant under §3186, the requesting state’s agents take custody and the person is physically transferred. The rule of specialty then limits prosecution to the offenses for which extradition was granted.
How long does the extradition process take?
There is no fixed timetable. Duration depends on how fast the requesting state files documents, whether the person is detained, how contested the §3184 hearing is, whether habeas review is pursued, and how long the Secretary of State takes to decide. A voluntary waiver can shorten it significantly.
