Mexican Citizenship by Naturalization

After enough time as a legal resident, foreigners can apply for Mexican citizenship by naturalization through the Secretaría de Relaciones Exteriores (SRE). Successful applicants receive a Mexican passport, full voting rights, and — in most cases — can keep their original nationality.

Who qualifies for naturalization?

Naturalization is open to legal residents — Temporary or Permanent — who have lived in Mexico for a qualifying period, can demonstrate basic Spanish and knowledge of Mexican history and culture, and have no serious criminal record. Time spent on a tourist permit (FMM) does not count.

Residency paths to citizenship

Standard route

Five continuous years of legal residency (Temporary + Permanent combined) before filing.

Spouse of a Mexican

Two years of legal residency plus two years of marriage to a Mexican citizen, living together in Mexico.

Latin America & Iberia

Nationals of Latin American countries, Spain, Portugal, and the Philippines can apply after just two years of residency.

Core requirements

  • Valid Temporary or Permanent Resident card for the full qualifying period.
  • Physical presence in Mexico: absences of more than 180 days in the two years before filing can reset the clock.
  • Clean criminal record from Mexico and from every country lived in during the past five years.
  • Basic conversational Spanish.
  • Passing score on the SRE's Mexican history and culture exam.
  • Filing in person at an SRE office in Mexico — the process cannot be started from abroad.

Spanish & history exams

SRE administers two evaluations. The Spanish exam is a short oral interview confirming you can hold a basic conversation. The history and culture exam is a written multiple-choice test drawn from an official published study guide covering key events, symbols, geography, and civic institutions. Applicants over 60, under 18, or with certain disabilities are generally exempt.

Recent CURP printout.
Proof of physical presence: entry/exit stamps or INM movement report.
