🇲🇽 Mexico · Citizenship
Naturalization rules: required residence years, language and civics requirements, and each country's dual-citizenship policy.
Quick answer
In Mexico you can naturalize after 5 years of legal residence, reduced to 2 years for spouses of Mexicans, parents of a Mexican-born child, or nationals of Latin American and Iberian countries. You take exams on Spanish, Mexican history and culture (with age exemptions). Mexico permits dual nationality. Applications go to the Ministry of Foreign Affairs (SRE).
Mexican naturalization is handled by SRE under the Nationality Law. Ordinary naturalization generally requires five years of residence, with shorter two-year routes for specific cases such as Latin American or Iberian nationals, marriage to a Mexican citizen, or having Mexican children.
- Nationality Law Article 20 sets the general five-year residence rule and lists shorter exceptions.
- Applicants must prove Spanish ability, knowledge of Mexican history and integration into national culture under Article 19.
- Mexico permits dual nationality in practice, but applicants should verify effects in any other country of nationality.
