Of every reason a foreigner ends up applying for Brazilian residency, a relationship with a Brazilian citizen or resident is one of the most common, and one of the most frequently mishandled, because the legal requirements don’t map neatly onto how people actually describe their relationships. “We’re together” isn’t a legal category in Brazilian immigration law; “casamento” (marriage) and “união estável” (stable union) are, and which one applies to your situation changes what you need to prove and how.
This guide covers both routes, plus the reunification categories that extend to children and, in some cases, parents.
The legal basis
Family reunion residency in Brazil is governed primarily by Portaria Interministerial nº 12/2018, issued jointly by the Ministry of Justice and the Ministry of Foreign Affairs under the framework of the Lei de Migração (Lei nº 13.445/2017). It allows a foreigner to obtain residency based on a qualifying family relationship with a Brazilian citizen or with a foreigner who already holds Brazilian residency, the “anchor” doesn’t have to be a Brazilian national in every case, though that’s the most common scenario.
Casamento (marriage): the more documented path
A legally registered marriage, whether performed in Brazil or abroad, is the most straightforward basis for family reunion, precisely because it produces a document (the marriage certificate) that’s easy to verify. If you married outside Brazil, that certificate needs to be apostilled in the country of issuance and then translated by a sworn (juramentado) translator in Brazil before it will be accepted by the Ministry of Justice or the Polícia Federal.
What trips people up here isn’t proving the marriage happened, it’s proving the marriage is current. If there’s an ongoing divorce process anywhere, or if the marriage was registered but the couple has been separated for an extended period without formalizing that, the application can run into problems, because the legal premise of the visa is an existing marital relationship, not a historical one.
União estável (stable union): the more evidence-heavy path
Brazilian law recognizes união estável, a stable union, as legally equivalent to marriage for most purposes, including immigration, and this recognition extends to same-sex couples, following Brazilian Supreme Court rulings that established marriage equality nationwide. Unlike a marriage certificate, a stable union usually isn’t a single document, it’s a declaração de união estável, which can be executed before a Brazilian notary (cartório) if both partners are available to do so, or supported through a broader package of evidence if the union needs to be demonstrated rather than formally declared.
That evidence typically includes: shared address documentation, joint financial accounts or shared bills, photographs spanning a meaningful period of the relationship, and, where available, statements from friends or family attesting to the relationship’s genuineness. There’s no fixed minimum duration written into the immigration rule itself for the residency application, but a longer, better-documented history of cohabitation and shared life meaningfully reduces the chance of the application being questioned.
A practical note on same-sex couples: because a formal união estável declaration or civil marriage is fully available and fully recognized for same-sex partners in Brazil, same-sex couples generally have the same two paths, casamento or união estável, as different-sex couples, with the same documentation standards.
Children and parents
Minor children of a Brazilian citizen, or of a foreigner who holds Brazilian residency, generally qualify for reunification-based residency alongside the primary applicant, with birth certificates (apostilled and translated, as with marriage certificates) as the core supporting document. Parents of a Brazilian citizen can, in some circumstances, also qualify under family reunification rules, though this is evaluated on the specifics of dependency and family structure rather than treated as automatic.
What the process looks like
- Assemble your civil documents. Marriage or birth certificates (or a declaração de união estável), apostilled in the country of origin if issued abroad, and translated by a sworn translator in Brazil.
- Confirm the anchor’s status. If the Brazilian partner or family member has Brazilian citizenship, this is straightforward. If they’re a foreign resident rather than a citizen, their own residency status needs to be current and properly documented.
- File the residency request with the Ministry of Justice (if applying in-country) or apply for the corresponding temporary visa at a consulate abroad before traveling, depending on where you and your partner currently are.
- Register with the Polícia Federal to obtain your CRNM once approved, within the standard 90-day (post-entry) or 30-day (post-DOU-publication) deadline.
A note on naturalization down the line
Marriage or a recognized stable union with a Brazilian citizen also matters beyond the initial residency application: it’s one of the specific grounds that reduces the standard four-year residency requirement for ordinary naturalization down to one uninterrupted year, provided the marital or union relationship remains intact at the time naturalization is requested. This is a meaningful long-term benefit worth factoring into planning even if citizenship feels far off at the outset.
Common problems worth avoiding
- Treating the relationship as self-evident. A genuine relationship isn’t automatically a well-documented one — start gathering evidence (shared accounts, correspondence, photographs with dates) well before you need it for an application.
- Skipping the apostille. A foreign marriage or birth certificate without an apostille (or, for a small number of countries outside the Apostille Convention, without the appropriate consular legalization) will not be accepted, no matter how official it looks.
- Assuming a tourist visa can be converted in-country. In most cases, arriving as a tourist and then trying to switch to a family reunification basis from inside Brazil isn’t straightforward — this needs to be planned before travel, not improvised after arrival.
- Letting an underlying divorce drag on unresolved. If either partner has an unresolved marriage elsewhere, this can undermine both a casamento- and, in some cases, a união estável-based application.
FAQ
Do we have to get married in Brazil, or can a foreign marriage count? A foreign marriage counts, provided the certificate is properly apostilled and translated, you don’t need to remarry in Brazil.
How long does a união estável need to have existed before it qualifies? There’s no fixed statutory minimum for the immigration application itself, but a longer, well-documented history strengthens the case significantly.
Can my partner sponsor me if they’re a foreigner living in Brazil, not a Brazilian citizen? In some cases, yes, provided your partner’s own residency is valid and properly documented, but this scenario deserves individualized review rather than assuming it works the same way as a Brazilian-citizen sponsor.
Does this visa let me work in Brazil? Generally, yes, family reunification residency does not carry the same work restrictions as, for example, the digital nomad visa.
What if we separate after I already have residency through this category? Residency already granted isn’t automatically revoked by a later separation, but it can affect future steps like conversion to indefinite status or naturalization eligibility tied to an ongoing relationship, this is worth discussing with a lawyer if your situation changes.
