On the loss of Mexican nationality acquired through naturalization

Mexican nationality acquired by naturalization is lost in the following cases:
I. For voluntary acquisition of a foreign nationality, for posing as a foreigner in any
public document, for using a foreign passport, or for accepting or using titles of nobility
that imply submission to a foreign State, and;
II. For residing in foreign territory for five consecutive years.
(Article 37 (B) of the Mexican Constitution.)

The loss of Mexican nationality acquired through naturalization will only affect the
person losing it.
(Article 29 Mexico. Nationality Law. 20 March 1998.)

Mexican nationality

Is defined in the 30th article of the Constitution of Mexico. The 32nd article establishes
that a separate nationality law is to regulate the exercise of the rights given by Mexican
legislation to those Mexicans that also possess another nationality and to establish the
norms to avoid the conflicts generated by the use of double nationality. This law was
last modified in 2005.

In general terms, Mexican nationality is based on both the principle of jus soli and the
principle of jus sanguinis. The Mexican constitution also makes a distinction between a
national of Mexico and a citizen of Mexico.

Loss of nationality and loss of citizenship

The 37th article of the constitution establishes that Mexicans by birth—natural born
Mexicans—cannot be deprived of their nationality under any circumstance,[5] such as,
and as defined in the Nationality law, the acquisition of another nationality. However,
naturalized Mexicans can lose their nationality if:

they voluntarily acquire another nationality, present themselves as foreigners or accept
nobility titles that imply a submission to a foreign State; and if they reside for five
continuous years in a foreign country.

Even though Mexican nationals by birth cannot lose their nationality under any
circumstance, Mexican citizenship, and thus its prerogatives, can be lost if a person:

  • accepts nobility titles from foreign countries;
  • serves in a foreign government without the authorization of the Congress of the
  • accepts or uses foreign distinctions, titles or functions, without the authorization of
    the Congress of the Union, with the exception of those that are literary, scientific
    or humanitarian in nature; helps a foreign citizen or government, and against
    Mexico, in any diplomatic claim or before an International Tribunal.
