How To Become a Mexican Citizen & Dual Citizenships

Mexican citizenship is acquired through a procedure called “Mexican Naturalization,” through which the Mexican state grants Mexican citizenship by delivering a document called a “Naturalization Letter” (Carta de Naturalizacion) to foreigners who meet the requirements established in the Regulations of the Nationality Law in Mexico. There is also the option for dual citizenship for those born to a parent from Mexico.

The goal here is to hold a Mexican passport. When you become a citizen of Mexico, you hold the same rights as others born in Mexico.

Some of the most important benefits are being able to vote during an election, not needing a fideicomiso when owning property in a restricted zone of Mexico, and not having to notify INM of a change of address, name, or job. There are other benefits, but these are some of the most popular.

The Different Ways You Can Become A Citizen in Mexico

There are different types of procedures to obtain Mexican naturalization, Mexican citizenship, or a Naturalization Letter. Some of them include

  • Naturalization by first becoming a resident
  • Dual citizenship by birthright if your parents were born in Mexico.
  • Naturalization for having Mexican children by birth.
  • Naturalization by marriage
  • Naturalization for having carried out outstanding works in cultural, technical, artistic, sports, or business matters.
  • Naturalization for being from a Latin American country or the Iberian Peninsula.
  • Naturalization for Refugees

Dual Citizenship Through Mexican Parents

To acquire Mexican citizenship through this procedure it is necessary to meet the requirements of Article 17 Section I of the regulations of the Mexican nationality law, which literally says:

The foreigner descendent in direct line of a Mexican by birth must demonstrate the relationship with the certified copy of the birth certificate issued by the Mexican civil registry office or Mexican consular office of the Mexican parent and exhibit the original of the current immigration document issued by the Ministry of the Interior, which certifies legal stay. You must also show evidence of residence in the country for two years immediately prior to the date of the application.

For Dual citizenship, the process usually starts at a Mexican Consulate or Embassy near you. You will be required to show proof of the direct lineage to a Mexican parent with their birth certificate(s). It’s also important to note whether or not the country you were born in observes dual citizenship. U.S. and Canadian citizens can have dual citizenship with Mexico. Or you can also do this process in Mexico through Registro Civil.

  • Have a temporary or permanent residence card with a minimum validity of 6 months.
  • Depending on the way by which you will obtain naturalization, the length of stay required in the regulations of the nationality law will vary. (Further down are the timeframes you must be in Mexico by eligibility type.)
  • Have proof or certificate of non-criminal record issued by competent authorities, both local and federal.
  • Must be in Mexico for the past 18 months out of the last 24 months. This means you cannot be out of Mexico for a period longer than 6 months out of the last 2 years.

  • Foreign birth certificate apostilled or legalized by the country of origin.

Naturalization For Residents

This type of naturalization is obtained based on Article 16 of the Mexican Nationality Law.

It applies to foreigners who have completed 5 continuous years in Mexico. This means the foreigner has had a continuous temporary or permanent Mexican residency card without expirations.

Also, at the time of the application, your card must be valid for more than 6 months.

Naturalization For Having Mexican Children by Birth

If a foreigner has a child in Mexican territory, the child will automatically obtain Mexican nationality, and the foreigner (father or mother) may request, in the first instance, permanent Mexican residence.

Once the parent has completed two years of continuous residence in Mexico, he/she will acquire the right to apply for the Mexican Naturalization process. This process is usually done within Mexico at your nearest INM.

Naturalization Through Marriage to a Mexican National

If a foreigner marries a Mexican or Mexican, he or she acquires a special right to obtain permanent residency or naturalize two years after having obtained the temporary residence.

You must also have proof of:

I. A copy of the marriage certificate issued abroad, translated, and apostilled. Or a copy issued by the Mexican Civil Registry office. In both cases, the date of the marriage must be at least two years prior to the submission of the application;
II.- To prove the nationality of the Mexican spouse, one of the following documents must be presented: a) a Birth certificate issued in accordance with the provisions of the applicable provisions; b) a Certificate of Mexican nationality; c) a Letter of naturalization, or d) In the absence of the evidentiary documents mentioned above, nationality may be accredited through any element that, in accordance with the Law and this Regulation, leads the Secretariat to the conviction that the assumptions were met.
IV.- Declaration under oath of truth, signed and presented personally by the Mexican spouse, that they live together and have established their marital domicile in national territory for at least two years immediately prior to the date of application.
V.- Present an original of a valid official identification with a photograph and signature of the Mexican spouse, including the Mexican passport, voter’s card, professional card (INE), National Military Service card, consular registration certificate, and citizen’s identity card.

This process is usually done within Mexico at your nearest INM.
