You’ve lived in Brazil long enough to qualify for naturalization. You speak the language, pay your taxes, and consider this country home. But when you start researching what documents you actually need to submit, you hit a wall of bureaucratic jargon, conflicting information, and outdated checklists.
This article cuts through the noise. Below you’ll find the complete, updated 2026 checklist of documents required for Brazilian naturalization — organized by applicant type, with real costs, official sources, and practical guidance on what can trip you up at the Federal Police (Polícia Federal) office.
The process is governed by Lei nº 13.445/2017 (the Brazilian Migration Law) and regulated by Decreto nº 9.199/2017. Both are complex. This guide translates them into plain English — so you know exactly what to gather, what to apostille, and what to translate before you apply.
What Is Brazilian Naturalization and Which Path Applies to You?
Brazilian naturalization is the legal process through which a foreigner becomes a Brazilian citizen. Under Lei nº 13.445/2017, there are four recognized paths: Ordinary (ordinária), Extraordinary (extraordinária), Special (especial), and Provisional (provisória). Each path has different residency requirements — and slightly different document lists.
The most common paths for expats and international families are:
- Ordinary Naturalization: Requires 4 years of continuous legal residency in Brazil. Reduced to 1 year if you have a Brazilian child, are married to or in a stable union with a Brazilian national, or hold a specific professional qualification recognized as beneficial to Brazil.
- Extraordinary Naturalization: Requires 15+ years of uninterrupted residency and no criminal conviction. No Portuguese language test required. If this is your path, read our detailed guide on Extraordinary Naturalization in Brazil.
- Special Naturalization: Available to employees of foreign governments or international organizations, and their dependents, under specific bilateral agreements.
- Provisional Naturalization: For foreign children or adolescents residing in Brazil, who can confirm citizenship upon reaching adulthood.
Regardless of which path applies to you, one rule is non-negotiable: you must hold permanent residency (residência permanente) before you can apply. Temporary visas do not qualify. If you are still on a temporary permit, your first step is to obtain permanent residency — our guide on Permanent Residency in Brazil explains how.
What Are the Core Documents Required for Brazilian Naturalization?
Every naturalization applicant — regardless of path — must submit a core set of documents to the Federal Police (Polícia Federal) via the Sistema de Naturalização (SINAL) portal on gov.br. According to Decreto nº 9.199/2017 and current Federal Police guidelines, the baseline document list for 2026 includes the following.
Identity and Civil Status Documents
- Valid passport — a copy of the photo page and all pages with Brazilian entry/exit stamps
- CRNM (Carteira de Registro Nacional Migratório) — your National Immigration Registration Card, which proves your legal residency status in Brazil. The 2026 renewal fee, per the Federal Police, is R$ 204.77 (approximately USD 38–42). See our full guide on CRNM Registration in 2026 for renewal steps.
- Birth certificate — original or certified copy, apostilled in the country of origin, with a sworn translation (tradução juramentada) into Portuguese
- Marriage certificate (if applicable) — same requirements: apostille + sworn translation
- CPF (Cadastro de Pessoas Físicas) — your Brazilian tax identification number, issued by the Receita Federal (Brazilian IRS). Free to obtain online at the Receita Federal portal; R$ 7.00 if processed via Correios (Post Office)
- Proof of Brazilian address — a utility bill, bank statement, or rental contract in your name, dated within the last 90 days
Criminal Background Documents: Documents for brazilian naturalization
- Criminal record certificate from Brazil — issued by the Federal Police (Polícia Federal), obtainable online at policiafederal.gov.br
- Criminal record certificate from your country of origin — must be apostilled and accompanied by a sworn translation into Portuguese. If you have lived in other countries for more than 1 year, you may also need certificates from those countries.
- Criminal record certificate from each Brazilian state where you have lived — issued by the state-level court (Tribunal de Justiça) of each state
Residency Proof Documents: Documents for brazilian naturalization
- Entry and exit history — a formal declaration of all entries and exits from Brazil, available from the Federal Police or via the e-MEC / SINAL system. This is used to verify continuous residency.
- Employment records or income proof — such as work contracts, CTPS (work booklet), tax declarations (Imposto de Renda), or bank statements showing financial activity in Brazil during the residency period
- Proof of livelihood — you must demonstrate you can support yourself financially in Brazil. Bank statements showing regular income or savings are typically accepted.
Language Proficiency
- Portuguese language proficiency — for ordinary naturalization, the Federal Police will conduct a basic oral interview to assess your ability to communicate in Portuguese. There is no formal written exam required for most applicants. Extraordinary naturalization applicants (15+ years) are exempt from this requirement under Lei nº 13.445/2017, Article 67.
What Additional Documents Are Required Based on Your Specific Situation?
Beyond the core checklist, your specific naturalization path triggers additional document requirements. Submitting incomplete supplementary documents is one of the most common reasons for delays or outright rejections, according to immigration lawyers who practice before the Federal Police.
If You Are Applying via the 1-Year Reduced Path (Spouse or Child of Brazilian)
- Brazilian spouse’s or partner’s RG (Registro Geral) — the Brazilian national identity card
- Brazilian spouse’s or partner’s CPF
- Marriage certificate registered in Brazil — if married abroad, the foreign certificate must be apostilled, translated, and registered at a Brazilian cartório (notary registry office) before submission
- Proof of cohabitation — utility bills, lease agreements, or a joint bank account in both names showing you live together. The Federal Police may request a declaração de convivência (cohabitation declaration) notarized at a cartório.
- If applying based on a Brazilian child: the child’s Brazilian birth certificate (certidão de nascimento) and proof that you exercise parental responsibility
If You Are a Portuguese Citizen (1-Year Path)
- Valid Portuguese passport or citizen card (Cartão de Cidadão)
- Proof of legal residency in Brazil for at least 1 year — via CRNM and entry/exit records
- Portuguese criminal record certificate — issued by the Direção-Geral da Administração da Justiça in Portugal, apostilled and translated
- Note: Portuguese citizens benefit from the Tratado de Amizade, Cooperação e Consulta (Treaty of Friendship between Brazil and Portugal), which grants them equal rights to Brazilians and reduces the residency requirement to 1 year. However, the document list is otherwise identical to ordinary naturalization.
If You Are Applying via Extraordinary Naturalization (15+ Years)
- Comprehensive residency evidence spanning 15+ years — this is the most document-intensive requirement. Acceptable evidence includes: annual tax declarations (declarações de Imposto de Renda), employment contracts, school enrollment records, property deeds (escrituras), and utility bills spanning the entire period
- Declaration of uninterrupted residency — a formal sworn statement (declaração) confirming you have not left Brazil for periods that break continuity (short trips abroad are generally acceptable)
- No criminal conviction certificate — both Brazilian and foreign, covering the full 15-year period
- Language proficiency interview is waived for this path
If You Hold Professional Qualifications (Reduced Residency Path)
- Diploma or professional certificate — apostilled and translated
- Recognition of the diploma by a Brazilian federal university or the relevant professional body — this process (revalidação) can take months and should be started well in advance
- Proof that your profession is recognized as beneficial to Brazil — a letter or documentation from the relevant federal ministry or professional council (conselho profissional)
How Must Foreign Documents Be Legalized for Brazil?
Any document issued outside Brazil must go through two mandatory steps before it is accepted: apostille legalization in the country of origin, and sworn translation (tradução juramentada) into Portuguese in Brazil. Brazil joined the Hague Apostille Convention, so documents from member countries do not need full consular legalization — an apostille stamp is sufficient.
Here is exactly what this means in practice:
- Step 1 — Apostille: Take your original document (birth certificate, criminal record, marriage certificate, etc.) to the competent authority in your home country. In the US, this is typically the Secretary of State of the issuing state. In the UK, it is the Foreign, Commonwealth and Development Office. The apostille stamp confirms the document’s authenticity for use abroad.
- Step 2 — Sworn Translation: Once you have the apostilled document in Brazil, you must hire a tradutor juramentado (sworn public translator) registered with the state’s Junta Comercial (Commercial Registry). Translation fees are regulated by state and typically range from R$ 100 to R$ 250 per page. Never use an unregistered translator — the Federal Police will reject the document.
- Step 3 — Cartório Authentication (when required): Some documents require notarized copies (cópia autenticada) from a Brazilian cartório. Fees range from R$ 5 to R$ 30 per document depending on the state.
If your home country is not a member of the Hague Convention, your documents must be legalized through the Brazilian consulate in your country — a longer and more expensive process. Check the Itamaraty consular portal for country-specific legalization requirements.
How Does the Application Process Work Step by Step in 2026?
The naturalization application in 2026 is initiated online through the SINAL (Sistema de Naturalização) platform on gov.br, then completed with an in-person appointment at the Federal Police. The Ministry of Justice issues the final naturalization certificate (certificado de naturalização) after approval. The full process typically takes 12 to 24 months from submission to certificate, based on current Federal Police processing volumes.
- Step 1 — Obtain your CRNM and ensure permanent residency is active. Without a valid CRNM reflecting permanent residency status, your application cannot proceed. If you need to convert a temporary residency to permanent, start this process first — it can take several months. Our guide on Residency Visas in Brazil covers the conversion process.
- Step 2 — Gather and legalize all documents. Use the checklists above. Allow 4–8 weeks for apostilles from your home country and sworn translations in Brazil.
- Step 3 — Create or access your gov.br account. You need a Silver or Gold level (nível Prata ou Ouro) gov.br account to access the SINAL platform. This requires identity verification, which can be done via facial recognition through the app or in person at a bank or government agency.
- Step 4 — Submit your application on SINAL. Upload all required documents in PDF format. The system will generate a protocol number (número de protocolo). Keep this number — you will use it to track your application.
- Step 5 — Federal Police interview and biometrics. After reviewing your digital submission, the Federal Police will schedule an in-person appointment for biometric collection (fingerprints and photo) and a basic Portuguese language interview (for ordinary naturalization).
- Step 6 — Ministry of Justice review. The Federal Police forwards your file to the Ministry of Justice (Ministério da Justiça e Segurança Pública), which conducts background checks and issues the final decision.
- Step 7 — Naturalization ceremony and certificate. If approved, you will be notified to attend a naturalization ceremony (cerimônia de naturalização) where you take an oath and receive your certificate. You can then apply for a Brazilian RG (identity card) and passport.

What Are the Real Costs of Gathering Naturalization Documents in 2026?
The naturalization application itself is free — there is no government filing fee for submitting through SINAL. However, the cost of gathering, legalizing, and translating your documents adds up quickly. Based on 2026 data from the Federal Police, Receita Federal, and average market rates for sworn translators, here is a realistic cost breakdown.
| Item | Estimated Cost (R$) | Approximate USD |
|---|---|---|
| CRNM renewal (if needed) | R$ 204.77 | ~USD 38–42 |
| CPF registration (online) | Free | Free |
| CPF via Correios/consulate | R$ 7.00 | ~USD 1.30 |
| Sworn translation (per page) | R$ 100–250 | ~USD 18–46 |
| Cartório authentication (per document) | R$ 5–30 | ~USD 1–6 |
| Brazilian criminal record (Federal Police) | Free (online) | Free |
| State criminal record certificates | R$ 0–50 per state | ~USD 0–9 |
| Apostille fees (varies by country) | Varies | USD 10–100+ |
| Total estimate (typical applicant) | R$ 500–1,500+ | ~USD 90–275+ |
The biggest variable is sworn translation costs, which depend on the number and length of your foreign documents. A single birth certificate might be 1–2 pages; a full criminal background report from some countries can run 5–10 pages. Budget accordingly.
Legal fees for an immigration lawyer to guide you through the process are separate and vary by firm and complexity of your case. Given that a single document error can delay your application by months, many applicants find professional assistance cost-effective in the long run.
Frequently Asked Questions About Naturalization Documents in Brazil
Do I need to translate documents that are already in Spanish?
Yes. Even though Spanish and Portuguese are closely related, Brazil requires all foreign documents to be translated into Portuguese by a tradutor juramentado (sworn public translator) registered with the state Junta Comercial. There are no exceptions for Spanish-language documents. The Federal Police will reject any document that is not accompanied by an official sworn translation, regardless of the source language. Budget R$ 100–250 per page for this service.
My criminal record certificate from abroad has expired. How recent does it need to be?
The Federal Police generally requires that criminal record certificates be issued within 90 days of your application submission date. This applies to both Brazilian and foreign certificates. Since obtaining a foreign criminal record, having it apostilled, and getting it translated can take 4–8 weeks, you should time this step carefully. Request your foreign certificate last, once all other documents are ready, to avoid it expiring before you submit.
Can I submit photocopies of my documents, or do I need originals?
The SINAL platform accepts digital PDF uploads of your documents. However, the Federal Police may request original documents or notarized copies (cópias autenticadas) at your in-person appointment. As a rule, always keep originals accessible and have notarized copies prepared for all key documents. Cartório authentication fees are R$ 5–30 per document, depending on the state. Do not submit uncertified photocopies as standalone documents — they are not legally valid in Brazil’s Civil Law system.
What happens if I have a minor criminal record — does that automatically disqualify me?
Not necessarily. Under Lei nº 13.445/2017, ordinary naturalization requires that you have no conviction for a crime that would result in extradition under Brazilian law. Minor offenses, traffic violations, or convictions for which you have fully served your sentence may not be disqualifying — but this depends on the nature of the offense and is evaluated case by case by the Ministry of Justice. Extraordinary naturalization (15+ years) requires no criminal conviction at all. If you have any record, consult an immigration lawyer before applying.
I lived in multiple countries before Brazil. Do I need criminal records from all of them?
The Federal Police typically requires criminal record certificates from any country where you lived for 12 months or more during the past 5 years (for ordinary naturalization) or during the entire residency period (for extraordinary naturalization). The exact requirement can vary depending on the reviewing officer, so it is safest to obtain certificates from every country where you had significant residency. Each must be apostilled and accompanied by a sworn translation into Portuguese.
Will I lose my original nationality when I become Brazilian?
Brazil does not require you to renounce your original nationality as a condition of naturalization. Under Article 12 of the Brazilian Constitution, naturalized Brazilians have the same rights as native Brazilians, with only a few exceptions (such as holding certain public offices). However, whether you can retain your original nationality depends on the laws of your home country — not Brazilian law. Portuguese citizens, for example, can hold dual nationality freely under Portuguese law. Americans should consult U.S. State Department guidelines on dual nationality before naturalizing.
