Mexico Dual Citizenship: Can You Keep Both Passports?
Yes. Mexico allows dual citizenship, and the U.S. also allows dual nationality. The practical question is not whether you must choose one passport forever. It is how Mexico treats nationality, how the U.S. treats dual nationals, and which passport you should use when you travel.
This page is the clean English head-term guide. If you are actually trying to claim Mexican nationality through a parent or grandparent, see Mexico Citizenship by Descent and the supporting pages in that cluster. If you searched the Spanish phrase, keep Doble Nacionalidad as the concept companion.

Short Answer
If you are asking whether you can keep your current citizenship and still be Mexican, the answer is usually yes. Mexico permits dual nationality, and the U.S. does not require you to give up U.S. citizenship simply because you become Mexican by birth, descent, or naturalization.
The catch is that dual nationality is not just a legal label. It comes with rules about how you enter and leave each country, which passport you present, and which country’s laws apply when you are on its soil.
What Dual Citizenship Means
Dual citizenship means you are legally a national of two countries at the same time. You may have rights in both places, but you also owe obligations in both places. That is why the practical side matters: a dual national can easily be valid on paper and still make travel mistakes if they use the wrong passport at the border.
For Mexico, the key point is simple: if you are Mexican, you do not lose that status just because you also hold another citizenship. For the U.S., the same basic concept applies: the government allows dual nationality, even though it expects you to use a U.S. passport when entering or leaving the United States.
Does Mexico Allow Dual Citizenship?
Yes. Mexico has allowed dual nationality since 1998. The Mexican SRE also notes that whether you can hold another nationality depends on the laws of the other country involved.
That matters because Mexico may recognize you as Mexican, but another country may have its own rules about acquiring or keeping a second nationality. In other words: Mexico is not the only system you have to satisfy.
Born in Mexico: Jus Soli
Mexico uses jus soli, which means nationality by place of birth. In ordinary cases, if you were born on Mexican soil, you are Mexican by birth even if your parents were foreign. That is different from countries that rely mainly on bloodline or parentage.
This is the part people often miss when they search for “Mexican dual citizenship.” They may be thinking only about descent through a Mexican parent or grandparent, but Mexico also grants nationality to many people who were simply born there.
If your case is parent- or grandparent-based instead of birth-in-Mexico based, the details belong in the citizenship-by-descent cluster, not here.
Born Abroad to a Mexican Parent
If you were born outside Mexico to a Mexican parent, you may already have a Mexican nationality claim through descent. That is not the same thing as “maybe one day.” It is often a present-right issue that only needs to be documented correctly.
The usual mistake is treating every Mexico claim as if it were a generic nationality question. It is not. The legal chain matters. If the chain runs through a parent, the better starting point is Mexico Citizenship by Descent. If it runs through a grandparent, use the grandparent guide.
Passport Rules That Matter
Dual citizenship only becomes complicated when you travel.
- Entering or leaving the U.S.: the U.S. State Department says U.S. citizens must use a U.S. passport.
- Entering or leaving Mexico: Mexico expects Mexican nationals to identify as Mexican when arriving or departing.
- Traveling to a third country: you may be able to choose the passport that gives you the simplest visa treatment, subject to that country’s rules.
- Local law still applies: dual nationality does not create a legal exemption from the rules of the country you are physically in.
This is why dual citizenship is a status, not a shortcut. It can make life easier, but only if you use it correctly.
Why It Matters
For many MLL readers, dual citizenship is valuable because it lets you keep your current passport while adding Mexico as a legal base. That can mean property rights, easier family mobility, access to services, and a more flexible long-term plan if Mexico is part of your life.
It also matters for basic identity planning. If you are eligible for Mexican citizenship by birth or descent, there is usually no reason to frame it as a forced choice between countries. The right model is often “both, but with the correct paperwork.”
Who This Is Not For
This page is not the place to diagnose a broken descent chain. If your question is actually “does my Mexican parent need to be registered first?” or “can I skip a generation?”, start with the descent cluster pages. If your question is “how do I get the passport after I already qualify?”, use the passport-process page instead.
If you only want the legal concept in Spanish or English-Spanish phrasing, keep Doble Nacionalidad as the companion page. This page exists to own the English head term and the practical rules.

FAQ
Does Mexico allow dual citizenship?
Yes. Mexico has allowed dual nationality since 1998.
If I was born in Mexico, am I Mexican?
In ordinary cases, yes. Mexico uses jus soli, so birth on Mexican territory generally makes you Mexican by birth.
Do I have to renounce my other citizenship to become Mexican?
Usually no. Mexico permits dual nationality, so renunciation is generally not required just because you become Mexican.
Do I have to use a U.S. passport if I am American and Mexican?
Yes, when entering or leaving the United States. That is the U.S. rule for dual nationals.
Is dual citizenship the same as Mexican citizenship by descent?
No. Dual citizenship is the status of holding two nationalities. Mexican citizenship by descent is one of the legal ways to get that status.
