Strategy: Gather your criminal background check (from both Brazil and your home country) early, as these can take weeks to process.
Strategy: The Portuguese language proficiency requirement can be satisfied through a formal test or an interview at the Ministry of Justice. Prepare by practicing conversational Portuguese.
Important: Absences from Brazil exceeding a continuous period may reset or interrupt your residence clock. Keep records of all international travel.

Scenarios

#

A German resident who has lived in Brazil for 5 years, is married to a Brazilian citizen, and speaks fluent Portuguese applies for naturalization with complete documentation.

The application is approved in approximately 12-18 months. The applicant takes the oath and receives Brazilian citizenship.

Meeting all requirements and having complete documentation significantly speeds up the process.

An applicant files for naturalization after 3 years of residence, not meeting the 4-year minimum.

The application is rejected. The applicant must wait another year and refile.

Verify the exact residence requirement for your category before filing.

A long-term resident applies but cannot provide a criminal background check from their home country because the document is expired.

The application is delayed for months while the applicant obtains a fresh background check and has it legalized.

Start gathering documents from your home country early; international document authentication takes time.

Next steps

#
  • Receive a receipt protocol number (protocolo) upon submission.
  • Schedule and attend a biometrics appointment at a Federal Police (Polícia Federal) office, if required.
  • Await the decision on the naturalization application.
  • If approved, receive a CRNM card issuance.
  • Complete any additional steps as instructed by the Federal Police.
