How to Apostille Documents for Dual Citizenship Applications — A Detailed Guide for Mexico
By Orange County Apostille
Introduction: Why Apostilles Are Crucial for Dual Citizenship Applications
When applying for dual citizenship, countries such as Mexico, Italy, and Spain require applicants to authenticate their documents to ensure they are genuine and legally recognized. One of the most common ways to do this is through an apostille, a form of international certification accepted by countries that are members of the Hague Apostille Convention. An apostille certifies the origin of a public document (such as a birth or marriage certificate) so it can be legally used in another member country. This guide focuses specifically on how to prepare and apostille your documents for dual Mexican citizenship, a path often pursued by those with Mexican heritage or family ties.
1. Understanding the Legal Basis for Dual Citizenship with Mexico
Mexico allows dual nationality, meaning you can be both a U.S. and Mexican citizen simultaneously. According to Mexico’s Constitución Política de los Estados Unidos Mexicanos, individuals born in the U.S. to Mexican parents — or those with at least one parent or grandparent born in Mexico — are eligible to apply for Mexican nationality through descent (naturalización por sangre). Mexican law recognizes this right as long as the applicant presents authenticated proof of lineage.

2. Determining Your Eligibility for Mexican Citizenship
To apply for Mexican citizenship by descent, you must prove that at least one of your parents or grandparents was born in Mexico. This is typically done by submitting an apostilled copy of the relative’s Mexican birth certificate, as well as your own birth certificate showing the family relationship. You do not need to speak Spanish or renounce your U.S. citizenship.
If you’re not applying by descent but through naturalization (such as after residing in Mexico for a certain number of years), additional documents and processes are required, but the apostille process remains similar.
3. Documents You Will Need to Apostille
For a typical application for dual Mexican citizenship by descent, you may need to apostille the following U.S.-issued documents:
• Your birth certificate
• Your parent or grandparent’s U.S. naturalization certificate (if applicable)
• Marriage certificate (if used to establish lineage)
• Death certificate (if parent is deceased)
• Affidavits or court orders related to legal name changes or adoptions
Each of these documents must be original or certified copies issued by the state or federal government. Photocopies or scanned versions are not accepted.
4. Translating Documents for Use in Mexico
After obtaining apostilles, you must have each document translated into Spanish by a certified translator in Mexico or a translator registered with the Mexican Consulate in the U.S. Only certified translations are accepted during the application process. The translation must match the apostilled document exactly and may also require a “perito traductor” (court-approved translator) if submitting directly in Mexico.
To find certified translators approved by the Mexican government, consult your local Mexican Consulate:

5. Filing Your Application at the Mexican Consulate
Once your documents are apostilled and translated, you can submit your application at your local Mexican Consulate in the U.S. This is where the dual citizenship process takes place for most applicants living outside of Mexico. You will need to make an appointment in advance.
At the appointment, you’ll be required to present:
• Apostilled and translated birth certificate
• Apostilled and translated parent/grandparent’s Mexican birth certificate
• Valid identification (passport or ID)
• Completed citizenship application form
• Two passport-sized photos

6. Timelines and Processing Periods
Processing times vary depending on the consulate and your specific case. Typically, after submission, it may take 4 to 8 weeks for your dual citizenship certificate to be issued. In some cases, delays may occur due to documentation discrepancies, so it’s essential your apostilles and translations are 100% accurate.
It’s also important to note that once approved, you may apply for a Mexican passport immediately. Having a Mexican passport allows you to live, work, or own property in Mexico without a visa.
7. Common Reasons for Rejection or Delay
Even eligible applicants may face issues if:
• The documents are not apostilled properly
• There is a mismatch in names (e.g., middle name missing, name change not explained)
• Translations are not certified
• The parent’s Mexican birth certificate is not in proper format or is missing signatures
To avoid delays, always review your documents thoroughly and use a reputable apostille service provider, such as Orange County Apostille, who understands international requirements.
8. Why Apostilles Are Non-Negotiable for This Process
Mexico is a member of the Hague Apostille Convention, which means it does not accept simple notarizations or county-level certifications for foreign documents. Apostilles are mandatory for all U.S. public documents that will be used in legal, governmental, or immigration matters in Mexico. Without an apostille, your documents will be considered invalid.
