Can You Renounce Argentine Citizenship? What the Law Says

No. You cannot renounce Argentine citizenship. If you were born Argentine, Argentine courts treat your nationality as irrenunciable, and the citizenship law gives you no way to give it up. If you became Argentine by naturalization, a formal renunciation only suspends your political rights. In practice, once you are Argentine, you stay Argentine.

That is good news for most people, because Argentina also allows dual citizenship. It becomes a problem only if you later want to naturalize somewhere that requires you to give up your previous nationality. This guide explains the law, why it works this way, and what you can do.

The Short Answer

Why Argentine Nationality Can’t Be Renounced

Argentine nationality by birth comes directly from the constitution. Article 75(12) gives Congress the power to pass general laws on nationality and naturalization, subject to the principle of natural nationality, meaning nationality by birth. The law that implements it, Law 346, sets out how to become Argentine but contains no mechanism for ceasing to be one.

Argentina’s National Electoral Chamber has ruled on this directly. It held that a native Argentine cannot voluntarily renounce their nationality, because that would amount to a loss of nationality the constitution does not allow. The reasoning is simple: a nationality granted by the constitution can only be removed by the constitution, and the constitution provides no way to remove it.

The result is close to absolute. A native-born Argentine stays Argentine whatever they sign, wherever they live and whatever other passports they hold.

What About Naturalized Argentines?

Naturalized citizens are in a similar position. Argentina’s citizenship regulations treat a renunciation by a naturalized citizen as suspending the exercise of their political rights, such as voting, rather than ending their nationality.

So whichever way you became Argentine, there is no practical route back out. For anyone weighing Argentine citizenship, that permanence is the most important thing on this page.

When This Becomes a Problem

Most of the time, it never does. Argentina allows dual citizenship, so you can hold Argentine nationality alongside others. The conflict appears only if you later apply to naturalize in a country that makes you renounce your previous nationality first.

Several Latin American countries do exactly that. Panama asks naturalized citizens to renounce their prior nationality by oath. Nicaragua now requires foreigners to renounce their original nationality before naturalizing, except people of Central American origin. Honduras generally requires renunciation unless a dual-nationality treaty applies. Our citizenship renunciation tracker sets out the rules country by country.

For an Argentine, that requirement can be impossible to satisfy in full. You can sign the destination country’s renunciation, but Argentina will still consider you Argentine, and there is no Argentine document you can obtain that says otherwise.

Spain, Italy and Treaties

Treaties change the picture. Spain does not require nationals of Ibero-American countries, Argentines included, to renounce their previous nationality when they acquire Spanish nationality, so an Argentine can become Spanish without any conflict.

Argentina also has nationality conventions with Spain and with Italy, which settle which country’s law applies to people who hold both nationalities. If either country is part of your plans, check how the convention applies to your situation.

What You Can Do

• Check the destination country’s rules first. Ask whether it requires renunciation and what proof it accepts.
• Ask whether a renunciation declared before the destination country’s own authorities is enough, since Argentina will not issue a certificate of loss.
• Look for a treaty. Countries with dual-nationality agreements, such as Spain for Argentines, may not require renunciation at all.
• Get written advice from a lawyer in the destination country before you apply, because a refused naturalization can be hard to reverse.

Before You Become Argentine

If you are not Argentine yet, factor this permanence into your decision. Argentine citizenship brings a strong passport, MERCOSUR residence rights and dual citizenship, but it is a lifelong status. That matters most if you might one day want to naturalize in a country that requires renunciation.

For most people, it is not a deal-breaker. You can compare the routes in our guide to getting Argentine citizenship, see what the passport gives you in our Argentine passport benefits guide, and follow the new citizenship by investment program.

How Argentina Compares With the Rest of Latin America

Argentina is not alone. Costa Rica, Ecuador, Guatemala, Honduras and Uruguay also protect nationality by birth from being given up. At the other end, Brazil, Chile, Colombia, Peru, Paraguay, Venezuela, El Salvador, Belize and Cuba all provide a way to renounce. Panama, Nicaragua, Mexico, Bolivia and the Dominican Republic are partial or unclear cases. Our citizenship renunciation tracker explains each one, with the law behind it.

Frequently Asked Questions

Can you renounce Argentine citizenship?

No. Argentine nationality by birth is treated as irrenunciable, and naturalized Argentines cannot give it up voluntarily either. A formal renunciation by a naturalized citizen only suspends their political rights.

Why can’t native-born Argentines renounce?

Because the nationality comes from the constitution itself. Argentina’s National Electoral Chamber has ruled that only the constitution could take it away, and it does not. The citizenship law, Law 346, has no renunciation procedure.

Does Argentina allow dual citizenship?

Yes. You do not lose Argentine nationality by acquiring another, and you do not have to give up your current nationality to become Argentine.

What if another country requires me to renounce Argentine citizenship?

Check that country’s rules carefully before you apply. Argentina has no procedure that ends your nationality, so you cannot produce proof that it has ended. Some countries accept a renunciation declared before their own authorities; others will not naturalize you. Spain does not require Argentines to renounce at all.

Can I lose Argentine citizenship any other way?

Nationality by birth cannot be lost. For naturalized citizens, a renunciation only suspends political rights rather than ending their nationality.

Is Argentina the only Latin American country like this?

No. Costa Rica, Ecuador, Guatemala, Honduras and Uruguay also protect nationality by birth. See our citizenship renunciation tracker for all 20 countries.
