Overview

In principle, yes, but it is not recommended. If a Brazilian travels to Brazil with a passport of another nationality, the immigration authorities may treat him as a foreign citizen, subjecting him to the maximum length of stay allowed for non-Brazilians. In this sense, there are cases of Brazilians who traveled to Brazil with a foreign passport and, on the day of their return flight abroad, were fined by immigration for having exceeded their stay limit. This is general information only. The appropriate legal path depends on the facts, timing, and authority involved. Before taking action, confirm the current rules for your situation and obtain individual individualized legal guidance where appropriate.
