Can someone who does not consider himself a US citizen be extradited and punished for a US felony crime due to a US citizenship?

I was fascinated by the above linked question. Most of the material in response seemed to be about the idea that a person committed a crime in fact rather than by intention, and so their belief that they were not a US citizen was not legally important.

But, I wondered, since it was also stated that whether you are a citizen of a country is not a matter of your own opinion but of the laws of the country - could the US make a person a US citizen specifically to be able to charge them with a crime and possibly extradite them.

I think I am asking: is it really entirely up to the country to proclaim someone a citizen? When can you renounce citizenship? Einstein famously renounced German citizenship in 1896 when he was still a minor.

One of the comments had an example that is spot on --The Lord Haw-Haw case after the 2nd WW. An American who became a Naturalized German, was tried for and convicted of treason as a British citizen because the British declared that he was one. The moral justification for this does not concern me here. Just, that that was the legal ruling. He got the death penalty. So that pretty much covers the spectrum here.

    "When can you renounce citizenship?": When the country's laws allow it. But keep in mind: it is possible, and not particularly uncommon, for two countries to disagree about an individual's nationality.

  • You don't get to "consider yourself" a citizen, least of all of the US. If you are a US citizen in fact, the only way to terminate that citizenship is complex, starting with establishing bona fide citizenship in another country. Commented Jan 14, 2022 at 21:45

    @Harper-ReinstateMonica there is no requirement to establish another citizenship before renouncing US citizenship.

    @Harper-ReinstateMonica you misconstrue my motivation, but no matter. Furthermore, the statement I was correcting wasn't that terminating US citizenship is "complex," which is a matter of opinion, but that having another citizenship is a necessary condition, which is objectively wrong. Many countries do have such a condition; the US does not.

You can be extradited from Country A to Country B even if you are a citizen of neither. What matters is whether B can convince A to do it, which is typically on the basis of a treaty between them as well as provisions of both country's domestic criminal law.

If you committed a crime in B, then fled to A, your nationality is relevant to the extent that:

  • A might not extradite its own citizens, if you are a citizen of A
  • A might have an agreement with C, if you are a citizen of C, that C should have the chance to proscute you instead of B. (This is the Petruhhin doctrine in the case where A and C are EU countries and B is not.)

But you do not have to be a national of B in order for it to have jurisdiction over you in B's domestic criminal law - just as if you were still in B, they could arrest you in the normal way. They are thus entitled to request A's authorities to arrest you in A, and transfer you to B.

If your alleged crime was not in B, then their claim over you has to be on the basis that their domestic criminal law allows prosecution extraterritorially. This was the case when B was Spain, A was the United Kingdom, and the criminal was former Chilean leader Augusto Pinochet; while his status as a former head of state was relevant, as was whether the crimes were extraterritorial offences in the UK as well, his lack of Spanish nationality was not. A more topical example is B being the United States, A the United Kingdom, and the arrestee being Julian Assange, an Australian who is alleged to have committed various crimes under U.S. law (while not necessarily having been present in the U.S. at the time).

While all extradition relationships are different, a common thread of the criminal law in general is that what matters is the circumstances at the time of the alleged acts. Retroactively making you a citizen of B may not be satisfactory to A, to the extent that A's criminal law disallows making anything illegal retroactively. The supposed nationality grant by B might trigger provision's of A's domestic extradition law concerning requirements of due process, lack of political interference, and so on, and block the action.

But equally, renouncing your citizenship of B does not extinguish B's claim over you for acts you did while you were a citizen of B. This is again a feature of typical criminal law.

    This is a good answer (+1), but it would be better if it more clearly spoke to the circumstances hypothesized in the OP's linked question, wherein holding U.S. citizenship is a necessary element of the offense. Commented Jan 13, 2022 at 19:14

    Great answer (+1). I think you partly covered the objection of @JohnBollinger in the comment about retroactively making things illegal. The case where they make you a citizen and then wait for you to do something illegal still stands. But, I feel that your discussion about citizenship not actually being required anyway more or less fills in that gap. In effect, if a country did declare someone a citizen so they could prosecute they are doing the equivalent of declaring them a person of interest. They are putting a target on their back. If other countries go along with it - then it has force.

  • I think this answer is off topic. There are many cases where laws apply only to the citizens of that country, like treason or the sanctions against Cuba. So a case where the citizenship is relevant does exist. The case of Julian Assange is not relevant because he is accused of committing crimes across the border (inciting people in the US to reveal secret information).

Made a citizen?

Probably not. Citizenship that is not acquired at birth normally requires some active step on the part of the person.

Not know you are a citizen?

Sure. Plenty of people, particularly the children of immigrants, may have a citizenship they don’t know about or think they hold a citizenship they don’t.

This can lead to tragic consequences. For example, there are many cases of people who immigrated at a young age, say to Australia, and grow up believing they are Australian (or not even thinking about it). They commit an offence and, at the end of their sentence, are met by immigration officials and are deported because they aren’t Australian. If they are New Zealanders this is tough but at least New Zealand speaks English. It’s really bad if they are Hungarian and don’t speak a word of Hungarian.


You don’t need to be a citizen of a country to be extradited to it; you just need to have committed a crime in that country and be in another country.

Some countries will not extradite their own citizens as a matter of law. For example, if you are a Russian in Russia, you cannot be extradited to any country.

    The tragic consequences described in the last paragraph are by no means unique to Australia, of course. There is a less tragic consequence, more particular to Australia, that is known to certain former members of parliament.

  • When the Australian political matter hit the news, I thought: could I bribe an official in Elbonia to grant citizenship to an opponent of mine? Commented Jan 16, 2022 at 2:29


could the US make a person a US citizen specifically to be able to charge them with a crime and possibly extradite them.

This part of the question is based upon a false premise.

Extradition has little or nothing to do with citizenship.

If someone who is currently in the hypothetical country of Albia commits a crime under the laws of the hypothetical country Elbonia, and Elbonia requests that the person suspected of committing an Elbonian crime be extradited by Albia to Elbonia to face those criminal charges, Albia can and not infrequently will agree to extradite the suspect to Elbonia without regard to the suspect's citizenship.

Very few countries prohibit the extradition of their own citizens for crimes committed abroad which would be comparably serious crimes not subject to the death penalty in a foreign state. Likewise, one does not have to be a citizen of the state in which the suspect allegedly committed a crime in order to be extradited to that state to face criminal charges.

Generally speaking, Elbonia cannot deport Elbonian citizens in Elbonia for committing Elbonia crimes. But that doesn't prohibit Elbonia from extraditing an Elbonian citizen to Albia for committing an Albian crime.

Involuntary Citizenship

Each country determines its own rules for determining who is a citizen of that country and who is not.

These rules are frequently inconsistent with each other. On one hand, that means that it is frequently possible to be simultaneously a citizen of more than one country. On the other hand, that means that there are circumstances under which a person can become "stateless" and have citizenship in no country.

Most of the time, your citizenship is not a matter of personal choice. The vast majority of the time, your citizenship is initially automatically established in one or more countries at birth, either by the place where you are born, the citizenship of your parents, or both. Neither you nor your parents have any say in determining your citizenship at the time of your birth in most cases.

Once your citizenship is established at birth, a new citizenship may established by naturalization, and an existing citizenship may be renounced. Naturalization opportunities are frequently heavily regulated and limited, and there are significant barriers to renouncing one's citizenship, in part, to avoid the problem of people becoming stateless.

I think I am asking - is it really entirely up to the country to proclaim someone a citizen?


A country could decide under its own laws that you are have become its citizen without your input, and indeed, this actually isn't all that uncommon.

The U.S. retroactively made lots of people citizens of the United States when the 14th Amendment to the U.S. Constitution was adopted.

Many countries retroactively declare that people with ancestors who were citizens of that country are citizens of that country.

When can you renounce citizenship? Einstein famously renounced German citizenship.

Each country can decide when and under what circumstances its citizens can renounce their citizenship for purposes of its own laws. Einstein's renunciation of German citizenship probably wasn't legally valid under the laws of the Third Reich in Germany.

But other countries can treat someone who renounces a foreign citizenship as no longer a citizen of that country even if the country whose citizenship is renounced doesn't allow its citizens to do so. Einstein's renunciation of citizenship was treated as valid under U.S. law without regard to the position that the Third Reich in Germany would have taken on the question.

    This comes up quite often with compulsory military service. You can go to visit a country and they can decide that you're a citizen and must perform military service, even if you were born overseas and don't speak the language. Here's an article about Thailand.

    Agreed that extradition has little or nothing to do with citizenship, but the OP is asking about a circumstance in which citizenship is an essential element of the offense, so it comes in from that direction. If the person in question is not and never has been a U.S. citizen then they cannot have committed the offense in question. Commented Jan 13, 2022 at 19:19

    There is no good reason why the U.S. government (by a general law, rather than a bill of attainder) couldn't declare someone to be a U.S. citizen and then punish them for treason committed while that person was a U.S. citizen, without their consent to becoming a U.S. citizen, so long as the country where the suspect was located agreed to extradite them, a decision which wouldn't depend upon citizenship but might be influenced the availability of a death penalty sanction in treason cases.

    @Vikki. I think it's pretty well established that taking US citizenship it does not do so. Swearing to the US that one renounces other citizenships carries no weight to most other countries, except those who disallow dual citizenship and will revoke theirs when they find out you've taken the US's. Thus many naturalized US citizens retain their prior statuses, and this page from the US Dept of State pretty clearly acknowledges that: travel.state.gov/content/travel/en/legal/…

I’m not aware of a provision of U.S. law that allows a person whom the U.S. government agrees was never a citizen to be forcibly naturalized. One of the few crimes for which not being a citizen would be a defense, and therefore the government might try to prove that someone who claims not to be a citizen really is, is in a case of treason.

The most famous case of something like this happening was William “Lord Haw-Haw” Joyce in 1946. A famous Nazi propagandist chosen to host a radio show in English, he was captured at the end of the war and put on trial for treason. He then revealed that he had never been a British citizen at all, He had been born in America to Irish Unionist parents, lived in Britain for a time, picked up the accent, then became a German citizen in 1940.

The embarrassed prosecutors brought forward at trial that Joyce had lied to obtain a British passport. (And had fooled them, too.) In theory, they argued, he could have shown that passport in Nazi Germany and asked for British consular protection, during the Second World War, while being a wanted criminal in the UK. Therefore, they alleged he owed loyalty to the British crown and could be executed for treason. In essence, and over his strenuous protests, he was declared to be in the same legal jeopardy as a British citizen despite never having been one.

The three American cases similar to that had different outcomes. One of the two women nicknamed “Axis Sally,” Rita Luisa Zucca, was not prosecuted for treason because she had renounced her U.S. citizenship in 1941. Two other women were convicted of treason after the war for having made propaganda broadcasts (one of whom was later pardoned), but neither disputed that they were U.S. citizens, and both remained in the country after serving their sentences.

Some other countries do sometimes declare a person a citizen of their country against their will. For example, the People’s Republic of China has declared that “persons belonging to any of the nationalities in China shall have Chinese nationality,” and “the People’s Republic of China does not recognise dual nationality for any Chinese national.” You might think this would mean that Hong Kong residents who accepted British citizenship would lose their Chinese citizenship. The PRC’s interpretation is in fact that “the British Citizenship acquired by Chinese nationals in Hong Kong [...] will not be recognised. They are still Chinese nationals and will not be entitled to British consular protection[.]”

This used to happen more often in the past, including in America. For example, the U.S. and some other countries used to hold that a woman who married a foreigner lost her original citizenship and acquired his.

  • I particularly liked your comment about the Chinese citizenship as this seems at the least to allow for the scenario I am interested in here.

  • While US law does not provide for involuntary naturalization, there's nothing stopping the US from passing a law to naturalize someone involuntarily, subject to the usual procedure for enacting laws. The question "can the US do X" isn't the same as "does US law currently allow the US to do X."

    @phoog Well, the State Department or the Justice Department cannot do that, in the present tense, because the law does not allow it. You’re interpreting the question as some future hypothetical. Maybe there’s a case or precedent that would shed light on whether such a hypothetical law would stand up in court?

  • I doubt there's such precedent, since I doubt anyone has ever tried a stunt like the one contemplated in the question. I just wanted to point out that there are different levels of "can" that often become obscured in questions like this. There's statutory law, as this answer discusses, but also constitutional law and international law, which can further be broken down into that based on custom as opposed to treaty, and the latter can be distinguished by enforcement mechanisms or the lack thereof.

  • William Joyce, born 1906, was brought to Ireland at the age of 3 (1909). He acted and was treated as a British subject, receiving his first British passport on the 4th of July 1933 describing himself as a British subject by birth. It is also questionable whether he actually received German citizenship in 1940 (even with some of the exceptions to the normal nationalisation rules that existed during WWII). Commented Jan 15, 2022 at 7:20

First of all, you don't have to be a citizen of a country to be charged with a crime in that country, For example, if a Canadian came to the US and started shooting people they would be charged the same as if they were American. The only exception would be diplomatic immunity.

Extradition is a diplomatic thing. It has nothing to do with whether or not someone committed a crime.

    The first paragraph of this answer is correct. The 2nd is not. Extradition is the procedure by which a person accused in one country but found in another may be handed over to the accusing country for trial. It thus does have to do with crime, specifically with whether a person has been accused of a crime. In many cases the sending country insists on evidence supporting the accusation before handing over the accused. Extradition is provided for by treaty, but I would not call it a "diplomatic thing".
