Yes, the U.S. can charge you for a crime committed abroad, but only in specific circumstances: you are a U.S. citizen or resident and the statute reaches your conduct overseas, the crime targeted Americans or U.S. government interests, or Congress has written extraterritorial reach into the specific federal law you allegedly broke. The default is that federal criminal law stops at the border. The Supreme Court confirmed this in Morrison v. National Australia Bank (2010), holding that federal statutes apply only inside U.S. territory unless Congress clearly says otherwise.1Justia Law. Morrison v. National Australia Bank Ltd., 561 U.S. 247 (2010) The exceptions, though, are broader than most people realize.
When Your U.S. Citizenship Follows You
American citizens carry certain legal obligations wherever they travel. This is called the nationality principle, and it is the broadest basis for prosecuting conduct that happened entirely on foreign soil. Congress has used it to reach behavior like paying bribes to foreign officials, traveling abroad to exploit minors, and manufacturing drugs overseas for U.S. import.
The clearest example is the child sex tourism statute. Any U.S. citizen or lawful permanent resident who travels to another country and engages in sexual acts with a minor faces up to 30 years in federal prison.2Office of the Law Revision Counsel. 18 U.S. Code 2423 – Transportation of Minors Prosecutors do not have to show you traveled for that purpose. It’s enough that the conduct happened after you left the country.
The Foreign Corrupt Practices Act works the same way for citizens and residents. If you’re American and you pay a bribe to a foreign government official to win or keep business, you can be prosecuted in federal court no matter where the bribe changed hands.3Office of the Law Revision Counsel. 15 U.S. Code 78dd-1 – Prohibited Foreign Trade Practices by Issuers
When the Victim or Target Is American
The U.S. can also prosecute foreign conduct when Americans or U.S. government interests are on the receiving end. Two related principles do this work.
Under the passive personality principle, the fact that the victim was a U.S. national gives American courts a hook even if the perpetrator is foreign and the crime happened overseas. Federal law makes it a crime to kill or seriously injure a U.S. national abroad, but only if the Attorney General certifies that the offense was meant to coerce, intimidate, or retaliate against a government or civilian population.4Office of the Law Revision Counsel. 18 U.S. Code 2332 – Criminal Penalties Murder under this statute carries life imprisonment or death.
The protective principle covers threats to U.S. national security or government operations. Espionage aimed at classified American information, counterfeiting of U.S. currency abroad, and attacks on U.S. embassies or military installations can all be charged in federal court, even when no American citizen is directly involved on either side. The connection is to the U.S. government itself.
Federal Statutes That Reach Foreigners Overseas
Some federal laws are written broadly enough to reach non-citizens whose conduct occurred entirely outside the United States. If your case falls into one of these categories, being a foreigner does not shield you.
Foreign Bribery Through U.S. Channels
The FCPA’s long arm applies to any foreign person who uses American mail or banking systems to further a bribe.3Office of the Law Revision Counsel. 15 U.S. Code 78dd-1 – Prohibited Foreign Trade Practices by Issuers Routing a single wire transfer through a U.S. bank can be enough. Both parties can be foreign nationals operating in a third country, and federal jurisdiction still attaches if the payment touched American financial infrastructure.
Drug Trafficking Aimed at the U.S.
One statute specifically targets anyone, of any nationality, who manufactures or distributes controlled substances outside the United States while intending, knowing, or having reasonable cause to believe the drugs will be imported here.5Office of the Law Revision Counsel. 21 U.S. Code 959 – Possession, Manufacture, or Distribution of Controlled Substance Separate provisions under the Maritime Drug Law Enforcement Act cover trafficking on vessels in international waters, giving the Coast Guard authority far from U.S. shores. These are among the most common extraterritorial federal prosecutions.
Hacking Into U.S. Systems
The Computer Fraud and Abuse Act has been applied to foreign hackers who target computers located in the United States. Courts have found jurisdiction because the effects were felt on U.S. soil and because Congress signaled concern about foreign intrusions when it expanded the statute.
Military-Connected Civilians
The Military Extraterritorial Jurisdiction Act reaches Department of Defense civilian employees, military contractors and their subcontractors, and dependents of service members living abroad.6U.S. Department of Justice. Military Extraterritorial Jurisdiction Act of 2000 Any conduct overseas that would carry more than one year in prison if committed domestically can be charged in federal court. The statute fills a gap that otherwise let contractors escape prosecution when neither military courts nor the host country had clear authority.
Universal Crimes: Prosecution for Being Present in the U.S.
A narrow category of offenses is treated as so grave that any nation can prosecute them regardless of where they occurred or who was involved. Piracy is the oldest example. The modern list includes torture, genocide, and war crimes, and each statute has its own reach.
- Torture committed outside the U.S. can be prosecuted here if the accused is a U.S. national or is physically present in the United States, regardless of the victim’s nationality. The penalty is up to 20 years, or death if the victim died.7Office of the Law Revision Counsel. 18 USC 2340A – Torture
- Genocide can be charged when the accused is a U.S. national, a lawful permanent resident, a stateless person who lives in the U.S., or simply present in the country. Someone who committed genocide abroad and later entered the U.S. for any reason could face charges here.8Office of the Law Revision Counsel. 18 USC 1091 – Genocide
- The war crimes statute was amended in January 2023 to add jurisdiction over any person present in the United States, no matter the nationality of the victim or offender. Before the change, prosecution required the victim or offender to be a U.S. national, permanent resident, or member of the armed forces.9Office of the Law Revision Counsel. 18 U.S. Code 2441 – War Crimes
The U.S. does not send agents abroad to arrest suspected war criminals with no American connection. But if such a person enters the country, federal prosecutors have the legal authority to act.
Getting You Into a U.S. Courtroom
Having jurisdiction to charge is not the same as being able to try you. Prosecutors still have to get custody of the defendant and assemble admissible evidence from abroad.
The U.S. has extradition treaties with more than 100 countries. Almost all of them require dual criminality: the conduct must be a crime under the laws of both nations, and it must be considered serious in each.10U.S. Department of State. The Consular Role in International Extradition – Introduction Most treaties also include a political offense exception, letting the requested country refuse if it views the charge as targeting political activity. Some countries refuse to extradite their own nationals at all, which can leave U.S. prosecutors with charging authority but no realistic path to trial.
Evidence gathering runs through Mutual Legal Assistance Treaties. MLATs give prosecutors a formal channel to ask foreign authorities to locate witnesses, take testimony, execute search warrants, obtain documents or electronic records, and trace or freeze assets.11Federal Judicial Center. Mutual Legal Assistance Treaties and Letters Rogatory – Obtaining Evidence and Assistance from Foreign Jurisdictions Without an MLAT, prosecutors fall back on letters rogatory, which are slower diplomatic requests.
Does a Foreign Trial Protect You?
Not necessarily. A conviction or acquittal in another country does not automatically bar a U.S. prosecution for the same conduct. The Fifth Amendment prohibits being tried twice for the same offense by the same sovereign, but the U.S. and a foreign nation are separate sovereigns. The Supreme Court reaffirmed the separate sovereigns doctrine in Gamble v. United States (2019): because an offense is defined by a sovereign’s law, two sovereigns create two offenses even when the underlying conduct is identical.
In practice, federal prosecutors do not routinely retry cases after a foreign judgment. The Department of Justice’s internal Petite policy discourages duplicative prosecutions unless a substantial federal interest was not addressed by the prior proceeding.12U.S. Department of Justice. Justice Manual 9-2.000 – Authority of the U.S. Attorney in Criminal Division Matters – Prior Approvals Diplomatic considerations and basic fairness also weigh against it. The legal authority is there, though, and prosecutors have used it when they viewed the foreign proceeding as inadequate.
Constitutional Protections in an Extraterritorial Case
If you’re prosecuted in the U.S., you get a full American trial with American procedural protections. But the Constitution does not follow U.S. agents everywhere they operate during an investigation.
In United States v. Verdugo-Urquidez (1990), the Supreme Court held that the Fourth Amendment does not apply to searches by U.S. agents of property owned by a non-citizen and located in a foreign country.13Justia Law. United States v. Verdugo-Urquidez, 494 U.S. 259 (1990) Evidence seized abroad by U.S. agents without a warrant can be admitted in federal court, at least when the target is not an American citizen. For citizens abroad the analysis is more protective, but the boundaries remain unsettled.
Miranda warnings work similarly. Statements taken by foreign police during interrogations overseas are generally admissible in U.S. court without Miranda warnings, because American courts cannot control foreign interrogation practices. Statements obtained by actual coercion are excluded regardless of where they were taken. When U.S. agents participate in or direct a foreign interrogation, courts look at the circumstances more closely.
The Clock Does Not Always Run in Your Favor
Two federal rules can extend the time prosecutors have to charge you in a cross-border case. When prosecutors submit a formal request to a foreign government for evidence, the statute of limitations pauses from the date of the request until the foreign authority takes final action, up to a maximum suspension of three years per offense.14Office of the Law Revision Counsel. 18 U.S. Code 3292 – Suspension of Limitations to Permit United States to Obtain Foreign Evidence Separately, no statute of limitations runs against a person who is a fugitive from justice.15Office of the Law Revision Counsel. 18 USC 3290 – Fugitives from Justice Sitting in a country without an extradition treaty does not let you wait out the clock.
