01Who qualifies

Who qualifies, generation by generation

LIKELY

Can you claim Brazilian citizenship through a parent?

Citizen by descent

A child of a Brazilian parent is Brazilian and is registered at the consulate.

What changes the answer

  • LIKELY
    If someone in the line became a citizen of another country before the next person in the line was born

    Since October 2023 acquiring another nationality no longer ends Brazilian nationality, which is lost only on the person's express request; before then the loss had to be formally declared, so a parent's naturalization abroad rarely broke the line on its own. Constitutional Amendment 131 of 3 October 2023, amending Art. 12 §4, Art. 12 §4(II)

  • LIKELY
    If you don’t know whether anyone in the line naturalized elsewhere before the next birth

    Since October 2023 acquiring another nationality no longer ends Brazilian nationality, which is lost only on the person's express request; before then the loss had to be formally declared, so a parent's naturalization abroad rarely broke the line on its own. Constitutional Amendment 131 of 3 October 2023, amending Art. 12 §4, Art. 12 §4(II)

POSSIBLE

Can you claim Brazilian citizenship through a grandparent?

Citizen by descent, generation by generation

Nationality passes from parent to child without a generational limit, but each generation must be registered as a citizen for the next to claim through them. Your parent registers first; then you.

What would settle itWhether your parent (and grandparent, if needed) can be registered as Brazilian nationals first.

POSSIBLE

Can you claim Brazilian citizenship through a great-grandparent?

Citizen by descent, generation by generation

Nationality passes from parent to child without a generational limit, but each generation must be registered as a citizen for the next to claim through them. Your parent registers first; then you.

What would settle itWhether your parent (and grandparent, if needed) can be registered as Brazilian nationals first.

02Dates that matter

The dates that matter

  1. 2023
    October 2023

    Since October 2023 acquiring another nationality no longer ends Brazilian nationality, which is lost only on the person's express request; before then the loss had to be formally declared, so a parent's naturalization abroad rarely broke the line on its own. Constitutional Amendment 131 of 3 October 2023, amending Art. 12 §4, Art. 12 §4(II)

03Mothers’ lines

How mothers’ lines were treated

Brazil’s rule gives the same answer whether the line runs through a mother or a father.

04Keeping your citizenship

Dual citizenship with your home country

You keep your citizenship.

On every open route, the rule lets a citizen of the United States, Canada, the United Kingdom, Australia, New Zealand, Brazil, Argentina or South Africa keep that citizenship.

05The routes

Every route, and the law behind it

  • LIKELY
    Through a parent

  • POSSIBLE
    Through a grandparent

The law

What would settle an unsure case

  • Whether your parent (and grandparent, if needed) can be registered as Brazilian nationals first.

06The documents

The documents, as the rule lists them

Citizen by descent

Through a parent

  • Your parent’s Brazilian birth certificate or identity document
  • Your birth certificate, apostilled and translated
  • Your parents’ marriage certificate

Citizen by descent, generation by generation

Through a grandparent or great-grandparent

  • Your ancestor’s Brazilian birth certificate
  • Birth and marriage records for each generation, each registered at the consulate in turn

Most countries also want proof that no one in the line became a citizen elsewhere before the next birth: the naturalization record with its date, or a letter that none exists.

07What it takes

What it takes: time, cost, the hard part, who decides

Citizen by descent

Time
A few weeks to a few months for the consular registration (registro de nascimento); the Brazilian passport follows quickly.
Cost
About $150–350: consular fees, apostilles and certified translations of your U.S. records.
The hard part
None, really. Bring your parent’s Brazilian birth certificate and your own apostilled birth certificate to the consulate appointment.
Who decides
The Brazilian consulate for your address, through the Ministério das Relações Exteriores.
The first record
Your parent’s Brazilian birth certificate (certidão de nascimento), from The cartório de registro civil where they were registered, or the Brazilian consulate. Request the certidão from the cartório of record by mail or through Brazil’s registro civil portal, or ask the consulate to pull it as part of your registration. gov.br

How it’s filed

Where
The Brazilian consulate general for the applicant's place of residence, in person. U.S. network: Atlanta, Boston, Chicago, Hartford, Houston, Los Angeles, Miami, New York, Orlando, San Francisco and Washington (the consulate general in Washington, separate from the Embassy). Jurisdiction is by state, and by county in Florida (Miami: south Florida, Puerto Rico and USVI; Orlando: central and north Florida) and California (Los Angeles: ten southern counties; San Francisco: the rest). New York: 225 East 41st Street, New York, NY 10017 (cg.novayork@itamaraty.gov.br), found via WebSearch of gov.br/mre, not fetched directly; confidence: secondary, verified 2026-09-25. Atlanta, Boston, Chicago, Hartford, Houston, Los Angeles, Miami, Orlando, San Francisco and Washington remain unaddressed. office list
How
In person; you appear in person
Appointments
e-consular (each consulate has its own instance, e.g. ec-chicago.itamaraty.gov.br). Log in with a gov.br account or register with email and password (no CPF needed). Upload the documents; the consulate pre-checks them (Chicago quotes up to 10 business days), then opens scheduling in the same platform. Slot availability varies by post and is released in batches. An e-consular terms-of-use page (ec-toquio.itamaraty.gov.br/tos) requires that services be requested from the document holder's own gov.br account/CPF/email, prohibits third-party data-sharing, and lets the consulate invalidate a request made by someone not legally authorized to act for the applicant — read via a WebSearch snippet, not fetched directly; confidence: snippet, verified 2026-09-25.
Fee
No fee
Decision
2–17 weeks
What goes in the file (7)
  1. The e-consular request, submitted for pre-check with every document scanned
  2. The applicant's full (long-form) birth certificate listing both parents; apostilled if issued outside the consulate's country, translated if not in English, French or Spanish
  3. The Brazilian parent's Brazilian birth certificate (certidão from the cartório, or the consular certificate), and identity document with photo (preferably a Brazilian passport), original
  4. The other parent's identity document with photo, original
  5. The parents' marriage certificate, registered at the consulate first where they married abroad
  6. Adult applicant (18+): the applicant's own photo ID (passport), and two adult witnesses with photo ID, who may be relatives and need not be Brazilian
  7. Proof of address in the consulate's jurisdiction (unverified: asked by some posts to confirm jurisdiction)
What goes wrong (9)
  • The registration itself is free and done the same day at the appointment; the wait is the pre-check and the slot. The consular certificate comes with a CPF number for a minor.
  • Under 18: a Brazilian parent must appear as declarant (Law 6.015/73 lists who may stand in). 18 and over: the applicant is the declarant and appears with two adult witnesses; neither parent needs to attend.
  • A birth may be registered only once: not if it was already registered at another consulate or directly in a Brazilian cartório.
  • Do not transcribe a foreign birth certificate directly in a Brazilian cartório instead of registering at the consulate: that makes the nationality conditional on an option before a federal judge after age 18. The consular route gives Brazilian-born (nato) status outright.
  • After registration, transcribe the consular certificate at the Cartório do 1º Ofício do Registro Civil do Distrito Federal (Cartório Marcelo Ribas, SCS Quadra 8, Ed. Venâncio 2000, Bloco B-60, Sala 140/E, Brasília/DF, CEP 70333-900), by post with the original certificate and a prepaid return envelope; about 5 business days. The transcription is what makes the registration effective inside Brazil (for a Brazilian ID, CPF use and voting).
  • Children under 12 can do registration and first passport in one combined appointment at most U.S. posts.
  • Historical note: births abroad from 7 June 1994 to 20 September 2007 needed residence in Brazil plus an option; Constitutional Amendment 54/2007 restored consular registration and let those people register at a consulate. No generational cap applies.
  • From CA, GB, AU, NZ, ZA: the same registration at the Brazilian consulate or embassy for your residence, through that post's e-consular instance. Your birth certificate must be apostilled (unverified whether a post accepts its own country's certificate without apostille, as New York does); English needs no translation.
  • From AR: the Brazilian consulates in Argentina (e.g. Buenos Aires, Córdoba) register the same way; Spanish needs no translation.

Citizen by descent, generation by generation

Time
A few months per generation, since your parent must be registered as a Brazilian national before you can be.
Cost
About $300–700 across the generations: consular fees, apostilles and translations at each step.
The hard part
Your parent has to register as a Brazilian citizen first, which can mean tracking down an old or never-filed cartório record before your own registration can move.
Who decides
The Brazilian consulate for your address, then the Ministério das Relações Exteriores.
The first record
Your ancestor’s Brazilian birth certificate, from The cartório de registro civil of their birthplace. Write to the cartório of record, or ask the consulate to help locate it, with the ancestor’s name, parents’ names and approximate birthplace. gov.br

How it’s filed

Where
The Brazilian consulate general for each registrant's place of residence (see 'Citizen by descent'). A parent living in another consulate's district registers there. office list
How
In person; you appear in person
Appointments
e-consular. One request and one appointment per registrant; the child's request can only be submitted once the parent's consular certificate exists. See the Citizen by descent path for the e-consular terms-of-use finding on account/CPF-linked requests.
Fee
No fee
Decision
1–8 months
What goes in the file (4)
  1. Generation 1 (the closest living descendant of the Brazilian-born ancestor, usually your parent): the same consular birth registration, with the ancestor's Brazilian birth certificate, the parent's own birth certificate and the parent's marriage certificate
  2. If a Brazilian ancestor naturalized abroad before the next birth: the Ministry of Justice certificate that no loss of nationality was declared
  3. Generation 2 (you): the e-consular request, your long-form birth certificate, your parent's newly issued Brazilian consular birth certificate and ID, your parents' marriage certificate registered at the consulate, your photo ID, two adult witnesses
  4. Proof of address in the consulate's jurisdiction for each registrant
What goes wrong (4)
  • The same consular registration applies to each generation in turn: the parent registers first (as an adult declarant with two witnesses), and the parent's new consular certificate is then the Brazilian-parent document for the applicant's own registration.
  • A deceased parent cannot be registered as declarant; whether a consulate will register a living grandchild through a deceased, never-registered parent is decided case by case (unverified; expect a request to the Ministry of Foreign Affairs).
  • Before 3 October 2023, a Brazilian who voluntarily naturalized abroad could have loss declared by the Ministry of Justice; if a loss act was published before the next child's birth, the chain breaks there (reacquisition is possible but does not reach back). Check with the negative certificate.
  • Transcribe each consular certificate at the 1º Ofício in Brasília.

08Where the records live

Where each record lives, and how to ask for it

  • birth1889–2026

    The cartório de Registro Civil das Pessoas Naturais (RCPN) where the birth was registered; every cartório is connected to the national Central de Informações do Registro Civil (CRC), run by the Operador Nacional do Registro Civil (ON-RCPN)

    The birth is registered at the cartório of the place of birth (or of the parents' residence). If the town is known but not the cartório, the registrocivil.org.br portal routes the request to the right office; old rural registrations sometimes sit in a cartório of a neighbouring district that has since been split or merged.

    • Civil registration began nationally on 1 January 1889 (Decreto 9.886 of 7 March 1888). Earlier births are only in Catholic parish registers.
    • The portal issues second copies (2ª via) of the ordinary certidão (breve relato) in electronic form within about 5 business days, or on paper by post within about 10 business days inside Brazil. Fees are set by each state's emolument table, not nationally (unverified per state; typically tens of reais).
    • A certidão de inteiro teor (full transcript of the entry with all annotations) cannot be ordered through the portal as paper; it is requested at the cartório itself (in person, by a representative, or by email/letter to the cartório). Use the template for that.
    • unverified: whether the portal delivers paper certificates to a foreign address; the reliable route is the electronic certificate, or delivery to a relative or a despachante in Brazil.
    • Look at the margin annotations (averbações) on the inteiro teor: a marriage, a name change or a loss of nationality would be noted there.

    • Only needed when the Brazilian ancestor was born before 1889. A consulate registering a descendant usually wants the ancestor's civil certificate; for a pre-1889 ancestor, a later civil record (marriage, death, or a later Brazilian ID) that states Brazilian birth may be accepted instead. unverified: which consulates accept a baptism certificate.

    Ministério da Justiça e Segurança Pública, Departamento de Migrações: certificate that no loss of Brazilian nationality is recorded (certidão negativa de perda de nacionalidade)

    • The Arquivo Nacional issues only negative naturalization certificates; a positive certificate, or any file after 1959, comes from the Ministry of Justice (Departamento de Migrações), which also issues 'certidão positiva e negativa de naturalização'.
    • Also holds ship arrival lists (1875–1964) and foreigner registration files (1939–1988), useful for dating an immigrant ancestor.

About
$0–$60 a page

Brazilian consulates accept documents in English, French and Spanish without translation, so U.S., British, Canadian, Australian, New Zealand and South African records and Argentine records need none. Any other language needs a translation (in Brazil, by a tradutor público juramentado; consulates abroad state their own rule, unverified per post). The foreign birth certificate itself must be apostilled when it comes from a country other than the one the consulate is in; a U.S. certificate presented at a U.S. consulate is accepted without apostille at New York (verify for other posts).

The passport

Where
The same Brazilian consulate, requested and paid through e-consular after the birth registration (the booklet is a Polícia Federal passport issued by the consulate). Adults bring electoral clearance (quitação eleitoral, from the TSE website) and, for men from the year they turn 19 until 45, proof of military enlistment or exemption; a man registered as an adult abroad enlists at the consulate first.
