If you are a national from any country and have a Mexican parent or grandparent, this information applies to you.
Quick answer: You are Mexican by birth if one of your parents is Mexican. Since a 2021 constitutional reform, this is true even if that parent was born in the United States, so many grandchildren of Mexican-born grandparents qualify. You claim it by registering your birth at a Mexican consulate or a civil registry in Mexico, using your long-form birth certificate and proof of your parent’s Mexican nationality.
For millions of Mexican-Americans and U.S. residents with Mexican heritage, the question of Mexican citizenship carries profound personal significance. If you are a U.S.-born child of Mexican parents or grandparents, you may have more rights to Mexican nationality than you realize. Understanding and claiming your Mexican citizenship opens doors to property ownership, inheritance rights, family connections, and a deeper bond with your cultural heritage.
At Lozano Law Firm, we bring a unique perspective to Mexican citizenship matters. Attorney Alfredo Lozano is himself a first-generation American whose family emigrated from Sabinas, Coahuila, Mexico, and he is Board Certified in Immigration and Nationality Law by the Texas Board of Legal Specialization. In addition to obtaining his law degree in the United States, he also received legal training at ITESM (Tecnológico de Monterrey) in Monterrey, Mexico, gaining firsthand experience with Mexican legal systems. This combination of U.S. immigration expertise and Mexican legal knowledge positions our firm uniquely to assist families navigating the intersection of both countries’ citizenship laws.
Understanding Mexican Nationality Law
Mexico’s approach to nationality differs significantly from U.S. citizenship law. Mexican nationality can be acquired through birth (by blood or by territory) or through naturalization, and critically, Mexico does not require renunciation of Mexican nationality when acquiring foreign citizenship. This principle of non-renunciation creates opportunities for many U.S. residents to claim or reclaim Mexican citizenship.
Mexican Nationality by Birth
Under Article 30 of the Mexican Constitution, the following individuals are Mexican nationals by birth:
- Those born in Mexican territory, regardless of their parents’ nationality
- Those born abroad to at least one parent who is a Mexican national
- Those born abroad to at least one parent who became a Mexican national through naturalization
- Those born aboard Mexican vessels or aircraft, whether military or commercial
Since a reform that took effect in May 2021, a Mexican parent passes nationality by birth to a child born abroad even if that parent was also born outside Mexico. This means that if either of your parents is Mexican, including a parent whose own mother or father was born in Mexico, you may be entitled to Mexican nationality by birth, even if you were born in the United States and have lived here your entire life.
Dual Nationality: You Can Be Both American and Mexican
One of the most important developments in Mexican nationality law came with constitutional amendments that took effect on March 20, 1998, after which Mexicans by birth no longer lose their Mexican nationality when they become citizens of another country. This change has profound implications:
- For naturalized U.S. citizens born in Mexico: If you became a U.S. citizen on or after March 20, 1998, you kept your Mexican nationality, even if you believed you had renounced it in the U.S. naturalization oath. If you naturalized before that date, you can recover it with a Declaration of Mexican Nationality by Birth (Declaratoria de Nacionalidad Mexicana por Nacimiento) from a Mexican consulate.
- For children born outside Mexico to Mexican parents: You can claim Mexican nationality without affecting your U.S. citizenship.
- For grandchildren born outside Mexico to Mexican grandparents: You may have claims to Mexican nationality.
Like many other countries, the United States also recognizes dual nationality in practice, meaning you can hold both U.S. and Mexican citizenship simultaneously without jeopardizing either.
Benefits of Obtaining Mexican Citizenship
Claiming your Mexican nationality provides numerous practical and personal benefits:
Property Rights
Mexican law restricts foreign ownership of property in the “restricted zone,” meaning areas within 100 kilometers of borders and 50 kilometers of coastlines. This includes popular destinations like coastal Baja California, Cancún, and border cities. As a Mexican national, you can own property in these areas directly without the trust structure required of foreigners.
Inheritance Rights
Inheritance of property in Mexico can be complicated for foreign nationals. Mexican citizenship can simplify inheritance of property in Mexico, especially land in the restricted zone, which foreigners can hold only through a bank trust.
Business and Employment
Certain professions and business activities in Mexico are restricted to Mexican nationals. Citizenship removes these barriers and allows full participation in the Mexican economy.
Government Benefits
Mexican nationals may be eligible for social programs, healthcare benefits, and retirement programs available through the Mexican government and social security system.
Family and Cultural Connection
For many families, Mexican citizenship represents a connection to heritage, culture, and identity that transcends legal technicalities. Formalizing nationality can strengthen family bonds across generations and borders.
Travel and Consular Protection
Mexican citizens can obtain Mexican passports, providing an alternative travel document. Additionally, Mexican nationals traveling or residing abroad are entitled to consular protection and assistance from Mexican diplomatic missions.
Who Can Claim Mexican Citizenship?
The eligibility for Mexican nationality depends on your specific circumstances:
If You Were Born in Mexico
You are a Mexican national by birth, regardless of where you currently live or what other citizenships you hold. If you became a U.S. citizen through naturalization on or after March 20, 1998, you did not lose your Mexican nationality, even though the U.S. naturalization oath includes renunciation language. If you naturalized before that date, you can recover it with a Declaration of Mexican Nationality by Birth from a Mexican consulate. You may need to obtain documentation confirming your nationality, but you do not need to “apply” for something you already possess.
If You Were Born in the U.S. to Mexican-Born Parents
You are entitled to Mexican nationality by birth through your parent’s nationality. This applies whether one or both of your parents was born in Mexico. You will need to register your birth with Mexican authorities to obtain official recognition and documentation of your nationality.
If You Were Born Outside Mexico to Grandparents Born in Mexico
You may be entitled to Mexican nationality by birth through your parent, who is Mexican by birth through your grandparent. Since the 2021 reform this works even if your parent was born outside Mexico, but your parent’s birth usually must be registered with Mexican authorities first so you can prove their nationality.

The Process of Claiming Mexican Citizenship
The specific process depends on your situation, but generally involves the following steps:
Step 1: Gather Documentation
You will need to compile documents proving your claim to Mexican nationality, which typically include:
- Your birth certificate
- Your parents’ birth certificates (especially if claiming through descent)
- Proof of identity (passport, driver’s license)
- All foreign documents (issued outside Mexico) must be apostilled
Step 2: Apostille Foreign Documents
Because we file your registration directly with the Civil Registry in Mexico, documents issued in the United States must be apostilled to be recognized by Mexican authorities. In Texas, apostilles are issued by the Texas Secretary of State. Different documents may require apostilles from different states or the U.S. Department of State, depending on where they were issued.
Step 3: Obtain Certified Translations
Documents in English must be translated into Spanish by a perito traductor (certified translator) authorized by Mexican authorities. Translations must be accurate and complete. We will process these translations directly in Mexico once we start your process.
Step 4: Submit Application
We will submit your documentation to the Mexican Civil Registry authorities directly in Mexico. You do NOT need to attend an interview at the consulate; we will take care of the process for you to obtain your Mexican citizenship as a descendant of Mexican nationals.
Step 5: Receive Documentation
You will receive documentation of your Mexican nationality as follows:
- Inscription in the Mexican Civil Registry
- Mexican birth certificate
- CURP
You can then apply for a Mexican passport and other identity documents.
Timeline and Costs
Processing times vary depending on the complexity of your case and the completeness of your documentation. Generally, straightforward cases involving registration of birth for first-generation U.S.-born children of Mexican parents can be completed within a few weeks.
More complex cases involving older generations or missing documentation may take longer.
Costs include apostille fees, translation costs, government filing fees, and attorney’s fees for assistance with the process.
Common Challenges
Missing Documents
Family documents from decades past may be lost or difficult to locate. Mexican vital records (actas) can often be obtained from civil registry offices in Mexico.
Name Discrepancies
Differences in how names appear on various documents (due to translation, anglicization, or clerical errors) can complicate applications.
Proving Parental Nationality
If your parent never formally documented their Mexican nationality, you may need to prove their nationality as a prerequisite to claiming your own. This may require obtaining their Mexican citizenship first.
Complex Family Situations
Adoptions, name changes, multiple marriages, and other family complexities may require additional documentation and careful explanation to Mexican Civil Registry authorities.

Frequently Asked Questions
Can I get Mexican citizenship if one of my parents is Mexican?
Yes. Under Article 30 of the Mexican Constitution, a person born abroad to a Mexican mother or father is Mexican by birth. Since a reform that took effect in May 2021, this is true even if your Mexican parent was also born outside Mexico. You make it official by registering your birth with a Mexican consulate or a civil registry in Mexico. Once you are registered, the same rule lets you register your own U.S.-born children.
Can I get Mexican citizenship through my grandparents?
Often, yes, but nationality passes through your parent. If your grandparent was a Mexican national when your parent was born, your parent is Mexican by birth, and since the 2021 reform your parent can pass that nationality to you even if both of you were born abroad. Consulates require proof of your parent’s Mexican nationality, so your parent usually registers first. Cases involving a grandparent who became a U.S. citizen before March 20, 1998 need closer review.
Will claiming Mexican citizenship affect my U.S. citizenship?
No. U.S. law does not require you to choose one nationality, and the State Department says a U.S. citizen may become a citizen of another country without risking U.S. citizenship. You must still use your U.S. passport to enter and leave the United States, and Mexico’s Nationality Law requires Mexicans by birth to identify as Mexican when entering or leaving Mexico.
Did I lose my Mexican nationality when I became a U.S. citizen?
It depends on the date. If you became a U.S. citizen on or after March 20, 1998, you kept your Mexican nationality by birth automatically, even though the U.S. oath includes renunciation language. If you naturalized before that date, you lost it under the law in effect then, but you can recover it by requesting a Declaration of Mexican Nationality by Birth (Declaratoria de Nacionalidad Mexicana por Nacimiento) at a Mexican consulate.
What documents do I need to claim Mexican citizenship?
You will need your original long-form U.S. birth certificate, proof that your parent is Mexican (a Mexican birth certificate, certificate of Mexican nationality, or naturalization letter), and valid photo IDs. Requirements vary by office. When the registration is filed with a civil registry in Mexico, U.S. documents also need an apostille and a Spanish translation by an authorized translator (perito traductor).
Do I need to speak Spanish to get Mexican citizenship?
No. If you qualify as Mexican by birth through a parent, there is no Spanish language requirement, because you are documenting a nationality you already have. Spanish matters only for naturalization, the separate path for foreigners who become Mexican through residence or marriage. Mexico’s Nationality Law requires those applicants to prove they speak Spanish and know the country’s history and culture.
