Cuban Citizenship for Children & Grandchildren (Ley 172)

If you were born outside Cuba and your mother, father or a grandparent is Cuban, you may be entitled to Cuban citizenship by birth. As of 2026 the rules come from a new law, Ley 172, the Citizenship Law. This guide sums up what the official text says and how the process usually works.

This is general information, not legal advice. Check the requirements with your Cuban consulate before you start.

What Ley 172 is and when it applies

Cuba's National Assembly passed Ley 172 on July 19, 2024. It was published in the Gaceta Oficial No. 39 Ordinaria on May 5, 2026, together with the new Migration Law (171), the Foreigners Law (173) and the Citizenship Registry regulations.

Its Fourth Final Provision says it takes effect 180 days after publication. Counted in calendar days, that's around November 1, 2026, the date reported in the press. The only thing that took effect right away in May was a separate decree-law for investors and business, not the citizenship law.

Ley 172 repeals Decree-Law 352 of 2017 and Decree 358 of 1944, the old citizenship regulations.

Citizenship by birth vs. by naturalization

Cuban citizenship is acquired by birth or by naturalization (Article 2). Citizens by birth include:

• People born in Cuba, with some exceptions for children of foreign diplomats.
• People born abroad to a Cuban father or mother.
• People born abroad to a Cuban parent who lost Cuban citizenship, if they claim it.

Naturalization is for foreigners, such as permanent residents of five years or more, and for cases decided by the President (Articles 36–40). Children adopted abroad by Cuban parents also go through naturalization (Article 37).

Children born abroad

Article 30 sets two requirements:

• Your birth must be recorded in the Cuban Civil Registry, a step known as birth transcription.
• You must be the child of a Cuban citizen born in Cuba.

Article 2 refers broadly to "a Cuban father or mother," but Article 30, which governs the procedure, specifies that the parent was born in Cuba. If your parent is Cuban but was born abroad, see the grandchildren route below and ask the consulate about your case.

Citizenship is not automatic. You have to file an application with a declaration of intent to acquire Cuban citizenship by birth (Article 33). The Ministry of the Interior decides (Article 22) and issues a resolution granting citizenship by birth. That resolution is your proof of citizenship and is issued free of taxes (Articles 41–42).

Your parent holding another nationality doesn't affect your right (Article 7).

Grandchildren: what the law actually says

The law does cover grandchildren, with one condition. You can be Cuban by birth if you are the grandchild of a Cuban citizen born in Cuba and your parent is already a Cuban citizen by birth who was born abroad (Articles 22.1(b) and 30(c)).

In practice, your parent has to have obtained Cuban citizenship first, and you must prove it in your application (Article 33(f)). The law doesn't provide a direct route from grandparent to grandchild.

There's a special case for children of people who renounced, lost or were stripped of Cuban citizenship. They can apply once they reach adulthood, but must show three consecutive years of effective residence in Cuba (Article 34). Article 35 applies the grandchild rule to these cases with five years of residence. Its wording isn't fully clear, so ask about your specific case.

What's different from before

• The old "avecindamiento" requirement, which meant having to live in Cuba, was already dropped in 2017. Ley 172 doesn't bring it back for children or grandchildren, except in the Article 34–35 cases.
• For the first time, a single law expressly covers grandchildren, with the condition above.
• The law sets deadlines. The consulate has 20 days to forward your file, and the case is processed within 90 days, extendable by another 90 (Article 66). Unless stated otherwise, these are business days (Article 13). Real-world timing may differ.
• If you're turned down, you can file administrative appeals and then go to court (Articles 99–102).

Dual citizenship and "effective citizenship"

Getting another nationality doesn't cost you your Cuban citizenship (Article 14). But inside Cuba, only the Cuban one counts:

• In Cuba and at Cuban consulates, Cuban citizenship is the one in effective use, and you can't rely on a foreign one (Article 15).
• You must identify as Cuban when entering, staying in and leaving the country. If you live abroad, you prove it with a Cuban passport (Articles 14 and 43; Article 87 of Ley 171). See our Cuban passport guide.
• There are fines for entering or leaving as a foreigner when you are Cuban, or for not registering in the Citizenship Registry (Article 82). Using another citizenship for legal acts inside Cuba is also fined (Article 83).

Ley 172 doesn't address military service or similar obligations. If that's a concern, ask the consulate.

Renunciation, loss and deprivation

• Renunciation (Articles 46–50): you must be over 18, hold another citizenship, be abroad, and have no debts to the Cuban state and no criminal cases. You apply at the consulate in your country of residence, and it only takes effect once accepted.
• Loss (Articles 51–53): if citizenship was obtained fraudulently, or if a naturalized Cuban abroad doesn't reaffirm it at a consulate every three years.
• Deprivation (Articles 54–56): on the grounds in Article 55, by presidential decree.
• Recovery (Articles 57–61): allowed only once, with requirements.

Step by step

1. Gather your Cuban parent's documents: their Cuban passport and Cuban birth certificate. If you're applying as a grandchild, add proof that your parent is already Cuban by birth.
2. Legalize your foreign birth certificate as the consulate instructs, and have it translated into Spanish if needed.
3. Request the birth transcription at the consulate. This gets you a Cuban Civil Registry birth certificate.
4. File the citizenship application with the declaration of intent, yours or your parents' if you're a minor. If only one parent applies, bring the other's notarized consent.
5. If you plan to live in Cuba, add a notarized authorization from the owner of the home where you'll be registered.
6. Wait for the Interior Ministry's resolution, which the consulate will notify you of. Then apply for your Cuban documents, such as a passport (Article 24).

The exact document list may change once the law takes effect, so ask the consulate for the current version before you start.

MINREX Resolution 37/2026 updated consular fees from October 1, 2026. Press reports say birth transcription and the citizenship application are fee-exempt, but certificates, legalizations and passports are not. Confirm exact amounts with your consulate.

What about Spain's "grandchildren's law"?

It's a separate thing. Spain's "ley de nietos" (Democratic Memory Law 20/2022) let descendants of Spaniards apply for Spanish nationality. Its application window closed on October 22, 2025. For pending cases, check with Spain's Ministry of Justice or your Spanish consulate.

Frequently asked questions

Is my child born abroad automatically Cuban?

No. Your child qualifies if you're a Cuban citizen born in Cuba, but you need to transcribe the birth and apply. They become Cuban once the resolution is issued.

Can grandchildren of Cubans get Cuban citizenship?

Yes, if your grandparent was born in Cuba and your parent is already a Cuban citizen by birth. You'll need to prove your parent's citizenship.

Do I have to live in Cuba to get Cuban citizenship?

Generally no. Residence in Cuba is only required for children and grandchildren of people who renounced or lost citizenship (Articles 34–35).

Can I enter Cuba on my foreign passport if I'm Cuban?

Under the law, no. You must use a valid Cuban passport to enter and leave, and doing otherwise can lead to a fine.

Will I lose my other nationality by becoming Cuban?

Cuban law doesn't ask you to give it up, but that depends on your other country's laws.
