Family Unity Residency in Mexico: What's Really Happening in 2025
By Dez | My Deztination: Mexicos Trusted Residency + Relocation Expert
What is Family Unity Residency?
Family Unity (“Unidad Familiar”) is the process that allows a foreigner with legal Mexican residency to sponsor their spouse, child, or parent for their own residency card. Until recently, it was considered one of the easiest ways for couples and families to stay together in Mexico.
But in 2025, that “easy route” started to change
What’s Changed — and Why People Are Being Denied
Across Mexico, some INM (Instituto Nacional de Migración) offices have tightened documentation rules.
The biggest change:
INM offices are no longer accepting affidavits from the U.S. or Canadian Embassies that simply state a person’s previous or maiden name (One-and-the-same-name affidavit).
Instead, applicants must now show a complete, legally verifiable name trail from birth to present — including every marriage, divorce, adoption, or citizenship change — all with apostilled or legalized documents.
If any part of that trail is missing or inconsistent, Family Unity applications are being rejected or delayed for months.

Why This is So Inconsistent?
Each INM office — and even each officer — is interpreting the rules differently. Just like Mexican consulates in the U.S. and Canada, approvals now depend on officer discretion.
Here’s what my national network of immigration attorneys is seeing right now:
Region Current Policy (as of Oct 2025)
CDMX (Mexico City) Still accepting the “One-and-the-Same-Name Affidavit” from the U.S. Embassy, but INM now verifies each Mexican marriage certificate directly with the Registro Civil where the marriage occurred — adding 3–6 weeks.
Puerto Vallarta / Nuevo Vallarta No longer accepting affidavits or free-form letters. Must show apostilled birth, marriage, divorce, and death certificates for every name change.
Ajijic / Chapala / Guadalajara Require apostilled marriage and divorce acts and will sometimes accept court judgments showing legal name change progression.
Mazatlán / Querétaro / Monterrey Case-by-case; some officers accept affidavits, others do not. Delays common.
So, when you hear one facilitator say “no problem” and another say “denied,” both are technically right. The rules aren’t uniform — and that’s exactly why you need professional guidance.
“Immigration in Mexico is changing fast — but with the right guidance and a clear strategy, you can still make your move smoothly.
My team and I are here to help you understand the real rules, navigate the gray areas, and avoid surprises once you arrive. ”
Example: When It Gets Complicated
I recently helped a couple where the wife was born in Colombia over 60 years ago — and never issued a formal birth certificate.
She had a baptism record (apostilled) but it didn’t match her U.S. green card or marriage certificate. Because the names didn’t align, we faced challenges with INM refusing to accept the documents for Family Unity.
In cases like that, I help clients determine whether to:
Apply for their own visa through financial solvency at a Mexican consulate in the U.S./Canada (faster), or
Build a complete apostilled trail of documents and apply for Family Unity inside Mexico (possible but slower).
The New “Registro Civil” Verification Step
Even if your marriage certificate looks perfect, INM offices (including Mexico City) are now sending it to the Civil Registry where the marriage took place to double-check authenticity.
This adds 3 to 6 weeks to processing times — sometimes longer if the registry doesn’t respond quickly.

When Starting at the Consulate Is Easier
For many couples, it’s now faster to start the Family Unity process directly at a Mexican consulate in the U.S. or Canada.
Why?
Consulates validate your documents themselves, including marriage certificates and name changes.
Once approved, you enter Mexico with a visa and simply complete a “Canje” (exchange) for your residency card.
This bypasses most of the document disputes now happening inside Mexico.

Frequently Asked Questions
What is Family Unity Residency in Mexico?
Family Unity Residency (Unidad Familiar) allows foreigners with legal residency in Mexico to sponsor a spouse, child, or parent for their own residency card. But as of 2025, new INM rules have made the process more complex, with stricter documentation and inconsistent regional enforcement.
That’s why I created full-service Family Unity support — to help you gather the right documents and avoid costly mistakes.
Can I apply if my name has changed through marriage or immigration?
Yes — but you’ll need to show a complete, apostilled paper trail that explains every name change from birth to present. That includes marriage certificates, divorce records, adoption papers, and more. If your name history isn’t crystal clear, your application may be denied or delayed.
I help clients prepare a verified name trail and strategize whether to apply through Family Unity or consulate-based financial solvency.
Do all documents need to be apostilled?
Yes. Mexican immigration now requires that key documents — including birth and marriage certificates — be apostilled (or legalized, depending on the issuing country). These must also be translated into Spanish by a certified translator once in Mexico.
My team works with certified translators and helps ensure your documents meet current INM standards.
Is it better to apply for Family Unity inside Mexico or at a consulate?
It depends. In many cases, it’s now easier and faster to apply at a Mexican consulate abroad, where documents are verified upfront. Inside Mexico, INM may reject your application due to minor document issues or inconsistencies — even with embassy affidavits.
I help clients evaluate both options and choose the safest, smoothest path for their situation.
Do you offer Family Unity residency support in my city?
I work with trusted immigration facilitators and attorneys in 20+ cities across Mexico, including Puerto Vallarta, Mexico City, Guadalajara, Chapala, Ajijic, Querétaro, and more.
Whether you're applying in Mexico or abroad, I’ll help you understand what your local INM office is really asking for — and prepare you accordingly.
