Dual nationality in Cuba: what Law 172 requires and what fines it provides

Citizenship Law 172 took effect on November 1, 2026, after its publication in the Official Gazette on May 5 of that year. The law allows Cuban citizenship to be retained alongside another nationality and establishes rules for people appearing before authorities on the island. Its entry into force does not amount to a general prohibition of dual citizenship.

The highlighted obligation is to identify as Cuban before Cuban institutions when carrying out covered procedures. Holding another nationality or passport does not by itself eliminate Cuban citizenship or automatically change the status under which a person must appear before those authorities.

The central distinction is between having another citizenship and using it in certain official acts to present oneself as a foreigner. According to the available information, the first situation is permitted; the second may bring penalties in cases specified by law. They are not interchangeable forms of conduct, and confusing them may lead to a mistaken interpretation of the fines' scope.

One consulted report says fines may reach 200,000 pesos. That limit is associated with using foreign citizenship in certain circumstances, not merely acquiring or holding another nationality. The available material does not provide a complete breakdown of punishable conduct or establish what amount would apply to a particular action.

That lack of detail about applicable cases matters for people carrying out official procedures. Without a detailed list of affected procedures, the standards for establishing a violation and the corresponding process, it is impossible to predict precisely how each individual situation will be resolved. The general rule requiring a person to identify as Cuban does not replace those specifics.

Naturalizing in another country also does not automatically mean losing Cuban citizenship, according to the available information. The law separately addresses renunciation and deprivation of citizenship. Acquiring another nationality, renouncing Cuban citizenship and being deprived of it are therefore different scenarios and should not be presented as automatic consequences of the same act.

The law thus organizes two areas: the continuation of Cuban citizenship and the obligations tied to its use before authorities on the island. A person who retains that citizenship must present themselves as Cuban in regulated circumstances even if they also hold another nationality. The described consequences concern certain uses of foreign nationality, not its existence in itself.

In practice, the lack of detail about punishable circumstances means general information should not become a conclusion about individual cases. Available information distinguishes permitted dual nationality from uses that may receive a fine, but does not establish which specific documents or procedures trigger each penalty.

With the law now in force, the scope of punishable conduct, the method for establishing it and the application of fine amounts still require clarification. It is also important to understand the procedures for renunciation and deprivation, which the law regulates separately. Until those answers are available, it is prudent to follow the general obligation and avoid assumptions about each individual procedure.
