Extradition Countries: US Treaties, Refusals, and Rights

The United States has bilateral extradition treaties with more than 100 countries, and those treaties are the only legal basis on which the U.S. can compel another government to hand a fugitive over. Federal law is explicit on this: under 18 U.S.C. § 3181, the surrender-of-fugitives provisions apply only while a treaty with the relevant foreign government is in force.¹ The editorial notes to that statute list every country with an active bilateral treaty, along with the date it was signed and the date it entered into force.²

Which Countries Have Treaties With the U.S.

Western Europe is the densest concentration of treaty partners. Beyond individual bilateral agreements with countries such as France, Germany, and Italy, the U.S. signed a broader agreement with the European Union in 2003 that strengthened cooperation across EU member states with existing bilateral treaties.³ The United Kingdom has its own separate bilateral treaty, also signed in 2003, covering crimes punishable by at least one year of imprisonment in both countries.⁴

Canada and Mexico, the two closest neighbors, both operate under well-established bilateral treaties that handle a substantial share of U.S. extradition activity.⁵ The list reaches well beyond Western allies. Active treaties cover much of Latin America, parts of Africa, the Caribbean, South Asia, and the Pacific — Colombia, Egypt, the Philippines, South Korea, and Thailand are among them.

The full country-by-country table sits in the notes to 18 U.S.C. § 3181. Anyone checking whether a specific country is covered should consult that list directly, because treaty status can change with new agreements or amendments.²

Notable Countries Without a Treaty

Some of the world’s largest nations have no extradition treaty with the United States. China and Russia are the most prominent. China maintains extradition agreements with roughly 20 countries; the U.S. is not one of them.⁶ Russia has no bilateral extradition arrangement with the U.S. either, and the diplomatic relationship makes voluntary cooperation unlikely in most cases.

Much of the Middle East falls into the same category. The United Arab Emirates, Qatar, Saudi Arabia, Kuwait, Bahrain, and Oman all lack extradition treaties with the U.S. The UAE has signed a mutual legal assistance treaty covering evidence sharing and investigative cooperation, but that agreement does not cover extradition itself.⁷ Other non-treaty countries include Indonesia, Vietnam, Ukraine, Cambodia, and several nations across Central and East Africa.

“No Treaty” Doesn’t Mean Safe

The absence of a treaty removes the legal mechanism to compel surrender, but the U.S. still has options.

Some countries will surrender a fugitive as a matter of comity — courtesy rather than obligation — under their own domestic laws. The State Department’s Foreign Affairs Manual notes that while the U.S. itself generally requests or grants extradition only on the basis of a treaty, many other countries can extradite as a matter of comity.⁸ These requests depend on diplomatic relationships and the severity of the alleged crime.

Countries can also deport or expel someone without any extradition proceeding, typically when the person violates local immigration laws or is treated as a threat to national interests.⁸ U.S. authorities often coordinate with the host country so the person is expelled directly to American jurisdiction.

An Interpol Red Notice is a worldwide alert asking law enforcement in member countries to locate and provisionally arrest a wanted person. It is not an arrest warrant, and Interpol cannot compel any country to act on one.⁹ Each country decides independently whether to detain someone based on the notice. In practice, a Red Notice makes travel, banking, and open residence far more difficult across nearly 200 member countries.

What Makes a Crime Extraditable

Even with a treaty, not every offense qualifies. Nearly every modern U.S. extradition treaty uses dual criminality as its core requirement: the conduct underlying the charges must be a crime in both the requesting country and the country where the fugitive is found.⁸ The offense doesn’t need to carry the same name in both places. What matters is whether the underlying behavior is criminal in each jurisdiction.

Treaties also set a minimum punishment threshold, generally at least one year of imprisonment under the laws of both countries.⁴ Minor infractions won’t trigger extradition. The system is designed for serious criminal conduct: violent crimes, drug trafficking, large-scale fraud, terrorism, and similar offenses.

Older treaties sometimes listed specific extraditable offenses. The modern dual-criminality approach is more flexible and automatically reaches new categories, such as cybercrime and cryptocurrency fraud, without treaty amendments.⁸

Why a Treaty Country Might Still Refuse

Several recognized exceptions can block or delay an extradition even when a treaty applies and dual criminality is met.

Political Offenses

Most extradition treaties bar extradition when the alleged crime is political in nature. The U.S.-U.K. treaty states that extradition will not be granted for a political offense.⁴ The exception is narrower than it sounds. Modern treaties carve out terrorism, assassination of heads of state, war crimes, and crimes against humanity. Violence against civilians dressed up as political action typically doesn’t qualify.

Refusal to Extradite Own Nationals

Many countries, particularly civil-law jurisdictions, refuse to hand over their own citizens for prosecution abroad. France, Germany, Austria, and Poland either constitutionally or legislatively prohibit extraditing nationals. The usual alternative is domestic prosecution using evidence supplied by the requesting country. Not every country takes this approach. The U.S., the U.K., and Australia have no legal prohibition on extraditing their own citizens.⁴

Death Penalty and Life-Sentence Assurances

If a crime carries a potential death sentence in the U.S. but not in the country holding the fugitive, most treaties let the foreign government refuse unless the U.S. guarantees the death penalty will not be imposed or carried out. The U.S.-U.K. treaty includes exactly this provision.⁴ U.S. prosecutors routinely provide these assurances, though doing so limits sentencing options at trial.

Some countries push further and require assurances against life imprisonment. Mexico began requiring such guarantees after a 2001 decision of its Supreme Court. Costa Rica, Spain, and Portugal have similar requirements, with Portugal reportedly insisting on a maximum sentence of 20 years for extradited individuals.¹⁰ These assurances are harder for prosecutors to make than death-penalty pledges, because judges control final sentencing.

Torture Risk

Separately, the United Nations Convention Against Torture prohibits any party from extraditing a person to a place where there are substantial grounds to believe they would be tortured.¹¹ The U.S., as a party to the convention, must evaluate this risk before executing any extradition.

The Rule of Specialty

Once a country hands someone over, the requesting country cannot simply add whatever charges it wants. The rule of specialty, found in virtually every extradition treaty, limits prosecution to the crimes for which extradition was granted.⁸ If the U.S. extradites someone from Germany for wire fraud, prosecutors cannot then pile on unrelated drug trafficking charges without going back to Germany for permission.

There are exceptions. The surrendering country can waive specialty and consent to additional charges. The extradited person can sometimes waive the protection voluntarily, though not every country allows this. Offenses committed after the extradition are fair game. The U.S.-U.K. treaty also permits prosecution for lesser included offenses or charges based on the same underlying facts as the original offense.⁴

Rights of the Person Facing Extradition

People caught in the process do have legal protections, though they’re more limited than in an ordinary criminal case. The most significant is the ability to challenge extradition through a habeas corpus petition in federal court. That petition can argue the treaty doesn’t apply, the evidence is insufficient, or an exception such as the political offense bar should block surrender. The extradition hearing itself is not a trial on guilt or innocence; the judge evaluates only whether the evidence meets the treaty’s threshold.

Bail during extradition proceedings is rare. The Supreme Court has held that bail is available only in “special circumstances,” and lower courts read that standard narrowly — serious medical conditions that cannot be treated in custody are the kind of thing that qualifies.¹²

There is also a time limit. Under 18 U.S.C. § 3188, if a person certified for extradition is not surrendered and removed from the U.S. within two calendar months after commitment, that person can petition a judge for release; the judge will grant it unless the government shows sufficient cause for the delay.¹³ Treaties often mirror this concept on the requesting side. The U.S.-U.K. treaty requires the full extradition package to arrive within 60 days of a provisional arrest, or the person may be released.⁴
