Marriage to a Brazilian national may reduce the residence period required for ordinary naturalization to one year. It does not, however, confer nationality automatically or waive the other statutory requirements.
To use this reduction, the foreign national must demonstrate actual residence in Brazil for the required period and maintain the relationship with the Brazilian spouse, without separation in fact or legal separation, at the time naturalization is granted. The applicant must also demonstrate legal capacity to act in civil matters, communication in Portuguese and compliance with the criminal-record requirement. Law No. 13,445/2017, Articles 65 and 66.
Does Marrying a Brazilian National Entitle You to Brazilian Citizenship?
The residence period for ordinary naturalization is generally four years. The expression “Brazilian citizenship through marriage” refers to the possibility of using the marital relationship to reduce that period through a separate naturalization application. Law No. 13,445/2017, Articles 65 and 66.
Before that stage, the relationship may provide a basis for residence authorization through family reunification. That authorization allows the person to reside in the country; naturalization makes the applicant Brazilian. Neither the marriage certificate nor the National Immigration Registration Card (CRNM) replaces a naturalization decision.
The guide Residence Through Marriage to a Brazilian National explains the immigration stage in detail. This article focuses on the application for nationality.
How Is the One-Year Period Calculated?
The reduction concerns the period of residence, not the length of the marriage. The administrative rule takes account of residence for an indefinite term and requires actual residence in Brazil during the period immediately preceding the application. It is therefore not enough to count one year from the wedding, the first entry as a tourist or obtaining an individual taxpayer registration number (CPF). Decree No. 9,199/2017, Articles 221, 233 and 235.
A foreign national who has been married for several years but has only recently arrived in Brazil does not meet the requirement merely because the relationship is longstanding. Their immigration history must be checked and residence during the required period demonstrated.
A replacement CRNM does not, by itself, restart the calculation. The assessment considers the history of the authorization and registration, rather than only the date of the most recently issued card.
Must You Live Continuously in Brazil?
Residence must be real. Having property, a bank account or an available address in the country is not enough, on its own, to demonstrate that the person actually lives here. Decree No. 9,199/2017 expressly rules out property ownership as sufficient proof by itself. Decree No. 9,199/2017, Article 233.
Occasional trips abroad are permitted. For this purpose, Ordinance No. 623/2020 recognizes trips totaling less than ninety days per year. In an application relying on the reduced one-year period, entry and exit dates must be checked carefully. Ordinance No. 623/2020, Article 51.
Tenancy agreements, utility bills, professional ties, education records, bank documents and other evidence may form part of the proof. The documents taken together must enable residence to be traced throughout the period, including where some documents are in the spouse’s name. Ordinance No. 623/2020, Article 56.
Must the Marriage Continue Until Naturalization Is Granted?
Yes. The Migration Law requires the applicant to have a Brazilian spouse and not be separated from that spouse in fact or by law when naturalization is granted. This condition must remain satisfied during the assessment; it is not enough for it to exist on the day the application is submitted. Law No. 13,445/2017, Article 66, III.
The evidence includes an up-to-date marriage certificate and a joint declaration by the spouses that their union and shared life continue. The certificate alone may not reveal a separation in fact. The declarations and documents must reflect the couple’s actual circumstances. Ministry of Justice and Public Security (MJSP) — Documents for the residence-period reduction through marriage.
If separation or divorce occurs during the proceedings, the change must be reported and the legal basis reassessed. The applicant may have another basis for naturalization, such as a Brazilian child or completion of the ordinary residence period, but that depends on the requirements for that basis and the documents submitted.
Which Requirements Remain Mandatory?
The benefit available through marriage reduces the residence period. The other conditions for ordinary naturalization remain: legal capacity to act in civil matters under Brazilian law, the ability to communicate in Portuguese and no criminal conviction, or legal rehabilitation following a conviction in accordance with the law. Law No. 13,445/2017, Article 65.
How Do You Prove Your Portuguese Language Ability?
Celpe-Bras, Brazil’s examination of proficiency in Portuguese, is one form of proof, but not the only one. The regulations also accept certain diplomas and documents evidencing education in Brazil, passing Brazil’s bar admission examination (Exame de Ordem), and Portuguese courses that meet the regulatory conditions, among other alternatives. Ordinance No. 623/2020, Article 5.
Not every certificate from a private language course will qualify. Before choosing a course or submitting a diploma, the institution, type of course and documents required for that alternative must be checked. Marriage to a Brazilian national does not, for example, exempt a French spouse from proving compliance with the language requirement.
How Are Criminal Records Assessed?
The documentation includes certificates from the federal and state courts for the places where the applicant lived in Brazil during the last four years, as well as a criminal record document from the country of origin, subject to applicable exemptions. Reducing the residence period to one year does not automatically limit all the documentary checks to the most recent year. Ordinance No. 623/2020, Annex I.
Where there is a conviction, any legal rehabilitation and the documents from the relevant proceedings must be examined.
Which Documents Should You Prepare?
Preparation should follow the official checklist and the applicant’s history. It generally involves gathering:
- Identification: CRNM, CPF and passport or another document accepted for the applicant’s circumstances.
- Relationship with a Brazilian national: an up-to-date marriage certificate and documents proving the spouse’s Brazilian nationality.
- Continuing married life: a joint declaration and evidence consistent with the continuation of the union and shared life.
- Residence in Brazil: documents covering the required period and enabling immigration history and absences to be checked.
- Portuguese language: one of the forms of proof accepted by the regulations.
- Criminal records: the relevant Brazilian and foreign certificates, with additional explanations where necessary.
Discrepancies in names, recorded parentage, dates or marital status should be resolved during preparation. The official checklist accepts the CRNM even if expired, but the status of the residence authorization must still be checked. Ordinance No. 623/2020, Annex I. MJSP — Ordinary naturalization
What If the Marriage Took Place in France or Another Country?
A marriage celebrated abroad must be documented in a form usable in Brazil. Official guidance describes consular registration followed by entry of the certificate in the records of the competent Brazilian civil registry office. Ministry of Foreign Affairs (MRE) — Registering a marriage abroad
French public documents covered by the France–Brazil agreement are exempt from apostille and legalization requirements. This exemption includes, for example, marriage certificates covered by the treaty. A sworn translation by an authorized public translator, where required, and the steps for civil registration remain separate matters. Decree No. 3,598/2000, Article 23.
For documents from other countries, the applicable apostille, legalization or exemption rules must be checked. The guide Foreign Documents for Immigration to Brazil: Apostilles, Translation and Requirements addresses these formalities.
How Does the Naturalization Application Work?
The application is submitted through Naturalizar-se, the online naturalization system, with a form and supporting documents. After the documents have been checked, an appointment takes place at the Federal Police (PF) to present originals and provide biometric data. The application then proceeds to the Ministry of Justice and Public Security for assessment and a decision. Official Naturalizar-se service
While the application is being processed, the applicant must monitor notifications, keep their details up to date and respond to requests for additional information or documents. Applying for naturalization does not replace the steps needed to maintain lawful immigration status while a decision is pending.
The government service is free of charge, although certificates, translations and other preparatory steps may involve costs. The envisaged completion period of up to 180 days allows for a reasoned extension; it is not a guarantee that naturalization will be granted within that time. Official Naturalizar-se service. Decree No. 9,199/2017, Article 228.
Naturalization takes effect upon publication of the act in the Federal Official Gazette (Diário Oficial da União). Only after naturalization has been granted are the documents corresponding to Brazilian status arranged, in accordance with each authority’s procedures. Law No. 13,445/2017, Article 73.
Frequently Asked Questions
Can I Apply for Naturalization Once I Have Been Married for One Year?
Not necessarily. The applicant must complete the required residence period, prove actual residence and meet the other requirements. The wedding date alone does not determine when an application may be submitted.
Can Married Couples Living Abroad Use This Reduction?
An ordinary marriage to a Brazilian national does not waive residence in Brazil for ordinary naturalization. There is a special category for a person who has, for more than five years, been the spouse or partner in a legally recognized unmarried partnership (união estável) of an active member of the Brazilian Foreign Service or of a person serving the Brazilian State abroad. That category has its own requirements and does not apply indiscriminately to couples living outside the country. Law No. 13,445/2017, Articles 68 and 69.
Does an Unmarried Partnership with a Brazilian National Also Allow a Shorter Period?
Yes. The law covers a Brazilian spouse or partner. For a legally recognized unmarried partnership, the relationship must be proven in accordance with the procedural requirements and must continue until naturalization is granted, without separation in fact or legal separation. Law No. 13,445/2017, Article 66, III.
Must My Residence Have Been Granted on the Basis of Marriage?
The statutory reduction is linked to the relationship with a Brazilian national, rather than exclusively to the basis of the residence authorization. Someone who already holds residence for an indefinite term through another route may consider this reduction, provided they satisfy the actual residence requirement, prove the relationship and meet the other conditions. Law No. 13,445/2017, Articles 65 and 66. Decree No. 9,199/2017, Articles 221, 233 and 235.
Does Separation in Fact Matter Even Without Divorce?
Yes. The law refers to separation in fact or by law. Keeping the marriage formally registered does not, by itself, preserve the ability to rely on the marital relationship to reduce the residence period.
Must a French National Renounce French Nationality?
No. According to official French guidance, a French citizen who acquires another nationality is not required to renounce French nationality. Acquiring Brazilian nationality may therefore result in dual nationality. For nationals of other countries, the respective nationality rules must be considered.
