Óscar Miranda is a licensed Mexican attorney (cédula profesional 13195234) who handles the full path in English: choosing between the consular visa and in-country regularization, proving the relationship correctly, the two-year temporary card, the switch to permanent residency, and — if you want it — Mexican citizenship.

Residency Through a Mexican Spouse: How the Law Actually Works
Article 56 of Mexico’s Migration Law gives Mexican citizens the right to preservación de la unidad familiar — the preservation of family unity. Because of that right, the foreign spouse (or common-law partner) of a Mexican citizen can obtain temporary residency for two years. Once those two years have passed, and as long as the marriage or partnership still exists, the foreign spouse can obtain permanent residency. Article 55 applies the same two-step scheme when your partner is not Mexican but already holds permanent residency in Mexico.
Three things about this route surprise almost every foreign client:
You do not need to be married — common-law partnerships qualify
The law extends family unity to the concubino or concubina (common-law partner), but the relationship must be proven under Mexican civil law standards — and this is where most applications fail. Saying you live together is not enough; the shared life has to be documented the way the authority will demand it.
Marrying a foreigner in Mexico no longer requires an immigration permit
The old INM marriage permit disappeared with the current Migration Law. What the Mexico City Civil Registry does require is civil paperwork: the foreign fiancé’s birth certificate apostilled (or legalized) and translated by an expert translator authorized by the local Superior Court of Justice, a passport, proof of address, the prenuptial course and the corresponding fees — plus an interpreter at the ceremony if you don’t speak Spanish.
The marriage has to be real — and the INM can verify it
Permanent residency through this route is conditioned on the marriage or partnership still existing. Simulating a marriage to obtain papers means declaring false facts to an authority — which can constitute a crime and leads to cancellation of the immigration document. With a genuine relationship, on the other hand, this is one of the most solid immigration paths that exists in Mexico.

Two Doors In: Applying From Abroad vs. Regularizing Inside Mexico
Choosing the wrong entry route costs months. Everything depends on where the foreign spouse is and how they entered the country:
Door 1 — Family-unity visa at a Mexican consulate (spouse abroad)
If the foreign spouse is outside Mexico, the route is the family-unity visa at the Mexican consulate: an appointment plus a file that proves the relationship. A marriage celebrated abroad is proven with the marriage certificate, apostilled or legalized and translated where required. After entering Mexico with the visa, the spouse exchanges it for the temporary resident card.
Door 2 — Regularization inside Mexico (spouse already here)
If the foreign spouse is already in Mexico — as a visitor or even after their stay became irregular — Article 133 of the Migration Law recognizes their right to regularization as the spouse or partner of a Mexican citizen or resident. No need to leave the country: you prove the relationship, pay the applicable fine, complete the process before the INM and receive the temporary resident card through family unity. It is a right, not a discretionary concession.
In immigration matters, mistakes are not corrected on the fly — files get rejected and you start over. Picking the correct door, building the evidence of the relationship without defects, and arriving at the first appointment with a complete file is most of the work. For everything else the INM handles — visitor overstays, other residency types, deportation defense — see our immigration lawyer services in English.
Working on This Residency — and the Road to Citizenship
Work permission is not automatic. The temporary resident card through family unity gives you the right to live in Mexico and to enter and leave the country freely — but Article 52, section VII of the Migration Law makes the permit to work for pay subject to a job offer, authorized separately by the INM. If you plan to work, that filing should be prepared alongside the residency, not discovered afterwards. Permanent residency, by contrast, includes permission to work by law.
- At the two-year mark, you choose: switch to permanent residency (your original nationality stays untouched, no exam), or —
- Apply for Mexican citizenship. Article 20, section II of the Nationality Law lets a foreigner married to a Mexican citizen apply for naturalization after proving two years of residing and living together in the marital home in Mexico, with the remaining requirements before the Ministry of Foreign Affairs (SRE), including an exam. Citizenship means a Mexican passport and full rights.
- The timelines coincide — so the choice between permanent residency and naturalization is made with your real dates on the table, comparing what each route requires and what it gives you.
The most common document failures are apostilles and translations. Foreign marriage and birth certificates must be apostilled (or legalized if your country is not part of the Hague Apostille Convention) and translated by an authorized expert translator when they are not in Spanish. Files are rejected over a missing apostille far more often than over any substantive problem with the relationship — get the paperwork verified before booking anything.
Official 2026 Government Fees
| Concept | 2026 fee (MXN) | Notes |
|---|---|---|
| Temporary resident card, 1 year | $11,141 | With the 50% family-unity reduction: $5,570 |
| Temporary resident card, 2 years | $16,693 | With the 50% family-unity reduction: $8,347 |
| Regularization application (reception and review) | $1,847 | Applies only to the in-Mexico regularization route |
| Fine for irregular stay (if applicable) | $2,346 – $4,692 | 20 to 40 UMA, set case by case |
| Family-unity visa authorization before the INM | $248 | Plus the consular visa fee paid at the consulate |
The 50% discount almost nobody requests: family-unity applicants can request — before paying — the benefit in the last paragraph of Article 8 of the Federal Law of Fees (Ley Federal de Derechos), which cuts the resident card fee in half. If you pay the full amount at the bank first, the benefit can no longer be applied. Attorney fees are quoted separately after reviewing your case.
Initial consultation: $2,000 MXN (about $100 USD). You leave it knowing which door applies to you — consulate or regularization — with the exact document list for your case and the full plan to permanent residency or citizenship.
Common questions from foreign spouses
I married a Mexican citizen. Do I get permanent residency right away?
Not immediately. Article 56 of Mexico's Migration Law grants the spouse of a Mexican citizen temporary residency for two years. Once those two years have passed, you can obtain permanent residency — as long as the marriage still exists. The same two-step structure applies if your spouse is a foreign permanent resident of Mexico (Article 55). How long the paperwork itself takes depends on the route and the office handling your file, so treat any promise of exact dates with skepticism.
Can I work in Mexico with residency by marriage?
You can, but work permission is not automatic. Under Article 52, section VII of the Migration Law, a temporary resident may obtain a work permit subject to a job offer, authorized by the INM (National Migration Institute) in a separate filing. Permanent residency is different: it includes permission to work by law. If working soon is part of your plan, the work-permit filing should be prepared alongside the residency itself.
My spouse is in Mexico on an expired tourist permit. Can we fix this without leaving the country?
Usually yes. Article 133 of the Migration Law recognizes a right to regularization for anyone who proves they are the spouse or common-law partner of a Mexican citizen or of a foreign resident — even if their stay has become irregular. The process happens entirely inside Mexico: you prove the relationship, pay the applicable fine, and receive the temporary resident card through family unity. It is a legal right, not a discretionary favor.
We are not married — we live together. Does a common-law partnership count?
Yes. Articles 55, 56 and 133 of the Migration Law extend family-unity rights to the concubino or concubina (common-law partner). The catch is proof: the partnership must be documented under Mexican civil law standards, and this is exactly where most of these applications fail. A well-built evidence file of the life you share makes the difference.
Which documents cause the most problems?
Foreign civil documents. A marriage certificate issued abroad must be apostilled (or legalized, for non-Hague countries) and, if it is not in Spanish, translated by an authorized expert translator. Birth certificates face the same requirements. Getting the apostille and translation right before booking any appointment is the single best way to avoid having a file rejected and starting over.
When can I apply for Mexican citizenship?
Article 20, section II of the Nationality Law allows a foreigner married to a Mexican citizen to apply for naturalization after proving two years of residing and living together with their spouse in the marital home in Mexico, along with the other requirements of the process before the Ministry of Foreign Affairs (SRE), including an exam. Since the timeline matches the two-year mark for permanent residency, many clients compare both routes and choose based on their life plans.
