According to Article 30 of the Political Constitution of Mexico, Mexican nationality can be acquired by birth or by naturalization.
Likewise, a birth certificate is the document that every Mexican by birth must carry to prove their nationality, while those who are Mexican by naturalization require a certificate of naturalization for such purposes.
However, a Mexican citizen can hold dual or multiple nationalities, thanks to the Nationality Law enacted in 1998, an aspect of great importance for those who need a nationality other than Mexican.
What is Mexican dual citizenship?
Mexican dual citizenship is what allows Mexicans by birth to hold another nationality without any risk of losing their Mexican nationality, thanks to Mexico's Nationality Law, which has been in effect since 1998.
With Mexican dual citizenship, you can obtain an expansion of rights, as you will not only be a Mexican citizen, but you will also be treated as a national citizen of the country where you are headed and whose nationality you hold.
However, dual Mexican citizenship comes with a series of responsibilities that must be met. One of these is that, according to Article 12 of the Nationality Law, you must enter or leave Mexican territory as a Mexican citizen. Otherwise, you could face administrative sanctions.
Furthermore, before carrying out any procedure with any Mexican authority (including its consular offices), it is mandatory to identify yourself as a Mexican, because doing so as a foreigner would imply violating Article 13 of the Nationality Law, with the legal consequences that this entails.
Before traveling to another country of which you are a national (other than Mexico), it is recommended that you go to the consulate or embassy of that nation to learn about your duties and rights, since the Mexican government will not provide you with consular protection in that case.
Does Mexican-American dual citizenship exist?
Mexican-American dual citizenship exists because the current legal framework in this area in both Mexico and the United States does not prevent Mexicans from adopting U.S. nationality, nor does it prevent Americans from receiving Mexican nationality.
Mexicans naturalized as U.S. citizens must be loyal to both Mexico and the United States, and must use their U.S. passport to enter or leave the United States.
If you want to obtain Mexican-American dual citizenship, you must emigrate to the United States, apply for permanent residency in that country, and obtain U.S. citizenship.
How do you obtain Mexican dual citizenship?
To obtain Mexican dual citizenship, you must go to the Mexican consulate in the country where you are located, where they will advise you on the matter.
If you were born in the United States and your mother or father (or both) are Mexican, you can obtain Mexican nationality by processing it at the nearest consulate.
Requirements for obtaining dual citizenship
To do this, you must register the birth by presenting the following documents:
- Long-form birth certificate of the interested party.
- Valid identification document of the interested party.
- Both parents must appear at the registry regardless of whether they are married or not.
- Parents' birth certificates.
- Official photo identification of the parents.
- Marriage certificate (if the parents are married).
In conclusion, a Mexican citizen can hold multiple nationalities because it is permitted by law. Furthermore, one can obtain Mexican citizenship either through naturalization or by being the child of Mexican parents.
