Mexico and the new naturalization rules in 2026: who will be rejected?

Mexico remains one of the most open countries in Latin America for immigration and citizenship. However, starting in 2026, new naturalization rules will come into force that significantly narrow the pool of eligible applicants for a Mexican passport. These changes are aimed at strengthening internal security and tightening control over migration flows. In this article, we break down who will be affected, what new requirements will apply, and how to meet them in order to successfully obtain Mexican citizenship in 2026.

From 2026, the Mexican government is introducing stricter requirements for citizenship applicants:

1. Enhanced background checks
Applicants will be required to provide expanded police clearance certificates not only from their country of citizenship, but from all countries where they have lived for more than six months over the past 10 years.
2. Stricter control of legal stay
Any violation related to illegal entry or breaches of immigration rules will constitute grounds for denial of citizenship.
3. Mandatory Spanish language proficiency
Applicants must pass a Spanish language test at a minimum B2 level under international standards.
4. Exam on Mexican history and culture
The exam will include questions on Mexican history, the constitution, geography, and cultural traditions.
5. Continuous residence requirement
Applicants must reside in Mexico for at least five uninterrupted years under a valid residence permit. Any absence exceeding 90 consecutive days will invalidate the residence period.

Under the 2026 rules, the following individuals will be excluded from the naturalization process:

• Individuals with any criminal conviction (including suspended sentences) within the past 10 years
• Those who have violated visa or immigration regulations in Mexico or other countries
• Applicants who have not completed five continuous years of lawful residence in Mexico
• Individuals who used or attempted to use forged documents
• Applicants who fail the language or cultural exams more than twice

Important: Even applicants with close relatives who are Mexican citizens will be subject to the same rules, except for cases of citizenship by birth.

To apply for citizenship under the new rules, applicants must submit:

• A valid passport and current Mexican residence permit
• Police clearance certificates from all countries of residence over the past 10 years
• Proof of income and tax compliance (SAT, RFC)
• Evidence of residence in Mexico (lease agreements, utility bills, contracts)
• Spanish language proficiency certificate (B2 level or higher)
• Proof of passing the cultural exam (issued by INM)
• Two 3×4 photos, application form, and proof of payment of government fees

Processing times remain lengthy:

• Preliminary document review: 3 months
• Main review process: 12–18 months
• Final interview and oath ceremony: up to 3 months

The government application fee is approximately 5,600 Mexican pesos (around USD 300 at the 2025 exchange rate). Exams and language certification are paid separately and typically cost USD 150–200.

Despite stricter rules, Mexican citizenship remains highly attractive:

• Visa-free access to over 160 countries, including the Schengen Area and the UK
• The right to live and work in Mexico without restrictions
• Access to public healthcare, education, and government programs
• Permission to hold dual citizenship
• Fast passport issuance after taking the oath

Mexico’s new migration legislation in 2026 requires more thorough preparation, stronger language skills, and a high level of legal compliance. If you are considering Mexican citizenship, start preparing early: organize your documents, improve your Spanish, and ensure full compliance with immigration laws.
