Assume a woman marries a foreign man for the purposes of him gaining citizenship. They stay married for a few years but never actually develop a real romantic relationship and by this point the woman has met another man she truly wants to marry for love. If she and this man get divorced so she can legally marry the man she actually loves would this affect the citizenship of the former green card husband? Or would he remain a citizen without any issue?

    As far as I'm aware, the UK doesn't have an immigration-related green card (although it does have a vehicle insurance related one).

    Marrying for the purposes of him gaining citizenship is fraud; in general the proceeds of fraud are recoverable, so there might be a mechanism to remedy the mistaken grant of citizenship. Commented Oct 28, 2023 at 9:14

    @TobySpeight indeed the naturalization laws I'm familiar with have provisions to cancel naturalization in such cases (or withdraw, revoke, etc.). There are far more naturalization laws that I don't know, however, but I imagine that such a provision is common. The Convention on the Reduction of Statelessness explicitly excludes such cases from its protection.

  • Thanks @phoog - I didn't know about that exclusion from the Convention, which would otherwise be an obstacle to revoking the ill-gotten citizenship. Commented Oct 28, 2023 at 15:15

    @TobySpeight for the curious, I add a citation; provision is in article 8(2)(b), which is short and to the point. There are other exclusions, notably for extended periods of residence abroad and in the way of transitional provisions established at the time of a state's accession to the treaty.

Naturalization obtained by fraud or misrepresentation, including misrepresentation in earlier applications for immigration benefits, can be revoked. This requires action on the part of the US government. The divorce would have no automatic effect on the citizenship of the naturalized spouse.

Assuming that the naturalized spouse had obtained lawful permanent residence (i.e., a green card) by virtue of a petition based on the marriage, the naturalized spouse could be denaturalized if US Citizenship and Immigration Services (USCIS) came to believe, and to be able to prove in court, that the marriage had not been genuine. This would be true even if the couple had not divorced.

The only effect of the divorce, therefore, is that it could increase the likelihood of USCIS becoming aware of the true nature of the marriage. There is no direct effect.

  • This is a pretty good answer but I think it would be better to emphasize how utterly exceptional such an action would be. Revocation is citizenship is very, very rare. The system as implemented puts scrutiny mostly on the green card status, mainly by having a separate "conditional resident" immigration class and green card validity period for marriages that are recent at the time of application, where the applicant must file for removal of "conditional" status 2 years after immigration.

We don't have "green cards" here, but I am assuming a "family reunion" visa, with your partner being a citizen married to you.

When you apply for that, you first get a temporary residence permit. This can be revoked, or simply not extended, based on conditions such as your marital status or "normal" crimes committed here. For example, getting caught with drugs might endanger that status.

If you still meet the conditions for family reunion, after a while (a few years: it depends on many things, let's just say it's somewhere between 3 and 5) your temporary residence permit runs out and you can apply for a permanent one. This can still be revoked later, but now we are talking about heavy stuff. Crimes against the constitution. Armed insurrection. Joining a foreign enemy army. Terrorism. Things that will land you in jail for a decade anyway. Normally, "permanent" actually means permanent, even if your marriage ends or you commit a "normal" crime. I think the actual plastic card expires every ten years, but there are no conditions on renewing it. Just bring the old one and your passport.

Again after a while (again, between 3 and 8 years depending on many factors: previous citizenship, marital status, language skills etc), you can apply for citizenship. Citizenship can never be revoked if you drop your original citizenship. Germany only revokes citizenship in very serious cases and only if the perpetrator had multiple citizenships to begin with. We are talking international incident level serious.

So a normal divorce has no effect once you have reached the "permanent" status and marriage is no longer a condition needed. Assuming the marriage was real in the first place. I don't think anybody would look twice if you got divorced after lets say 7 years - 3 years after your permanent residence permit. Life happens and it's not always pretty.

Now if you threw a party and got happily divorced the day after your permanent residence permit arrived in the mail, the authorities might check for fraud. And if they consider your marriage fraud, then it doesn't matter where in the process you are really. Citizenship built on fraud can be revoked up to ten years after you got it, even if it means you will then be stateless.

    Hmm, I don't think this is correct. Germany, afaict, has no law allowing citizenship to revoked other than for certain specified reasons: gesetze-im-internet.de/englisch_stag/englisch_stag.html - joining another country's armed forces being the one that stands out. Also, for married couples, it is 3 years of residence required (and two or more years of marriage at that point), the longer periods apply to other circumstances. Finally, if you are dishonest in applying (such as a fake marriage) the prohibition on statelessness does not apply. Commented Oct 28, 2023 at 11:01

    @JackAidley "I don't think this is correct": which part is incorrect? Nvoigt: regarding "Citizenship can never be revoked if you drop your original citizenship," it is not contrary to the Convention on the Reduction of Statelessness to make someone stateless by depriving them of a nationality that has been obtained by fraud, and Germany has accordingly enacted such a provision. See section 35(2).

    @phoog, the part "Germany only revokes citizenship in very crass cases and only if the perpetrator had multiple citizenships to begin with. We are talking international incident level crass." Commented Oct 28, 2023 at 14:38

    @phoog Wow, I did not know that, I thought that was universal. Thanks for noticing, I corrected it.

The timeframe for the procureur de la république to revoke a naturalization through marriage (Nationalité par déclaration, which you can apply to after 4 years of marriage) is 2 years of the date of the acceptance of the declaration

Any separation/divorce in the 12-month period following the acceptance of the declaration will automatically be treated as a suspicion of fraud and can lead to the newly-French having their citizenship revoked after an investigation and a favorable opinion by the Conseil d'état (the highest administrative court)

If the citizenship is sought through naturalization (Having lived 5+ years in France, having fought for the Foreign Legion...) instead of marriage, the divorce would likely not impact the proceeding (though the timeframe is the same)

After those 2 years, it is impossible for the citizenship to revoked unless, in the following 10 (or 15) years after acceptance of French nationality (a French national from origin can't be stripped of their nationality this way), and provided the holder has another citizenship, are committed :

  • Crimes et délits portant atteinte aux intérêts fondamentaux de la Nation (as listed in Book IV, title I of the Code pénal
  • Acts of terrorism
  • Crimes and delits, committed in a public capacity, against the administration itself (Book IV, Title III, Chapter II)
  • Haven't fulfilled the obligations of the national service (Census (between 16 and 25yo), eventual military service...)
  • Acts for a foreign nation that isn't compatible with holding French citizenship
