❓ Does an expired CRNM prevent Brazilian naturalization?

services%20serian%20visa

If you are a foreigner living in Brazil and dream of acquiring Brazilian nationality, it's very likely you've had this question about the validity of your CRNM (National Registry of Foreigners) for the Brazilian naturalization process.

👉 “My CRNM is expired. Can I still apply for naturalization?”
👉 “Will my application be denied because of this?”

Foreigners living in Brazil who have difficulty renewing their residence documents feel insecure and afraid when applying for Brazilian naturalization, especially Haitians and Africans living in Brazil.

⚠️ The truth is that an expired CRNM does not immediately mean that you have lost the right to Brazilian naturalization.  The individual migratory situation of each foreigner residing in Brazil must be considered, and not just the validity of the card in isolation.

📘 What is the CRNM and why is it important for naturalization?

🪪 What does CRNM stand for?

The CRNM (National Migratory Registration Card) is the document that proves that a foreigner has legal residence in Brazil. It replaced the old RNE.

On the CRNM you will find:

  • Type of residence (temporary or permanent)
  • Migratory registration number
  • Expiration date of the physical document
