Family reunion
This is the most used route and the most poorly prepared. What decides the case is not the family relationship itself, it is the documentary proof of it. Foreign certificates have to be apostilled and translated by a public translator. In a stable union, a declaratory deed on its own is rarely enough: the authority expects a body of evidence of life together over time.
Work
Two sides are involved. The Brazilian company has to prove the hiring and, on several grounds, obtain prior work authorization. On your side come your degree, proof of experience and criminal record checks. Coordinating both sides on the same timeline is what avoids doing the work twice.
Study
Residence follows the course: it starts with acceptance by the institution and is renewed in line with the course length. If you change course or institution, that has to be reported. Unreported changes create an irregular status without the student noticing.
Investment
This applies to investment in property or in a Brazilian company, with a minimum amount set by resolution of the Conselho Nacional de Imigração (National Immigration Council). Beyond the amount, the authority examines the lawful origin of the funds and, for a company, the investment plan and the jobs created.
Digital nomad
Created by Resolução CNIg nº 45/2021 for people who live in Brazil but work for clients abroad. It requires a contract or other proof of services provided to a foreign employer or client and proof of monthly income in foreign currency. It does not authorize employment with a Brazilian company.
Mercosur treaty
Nationals of Mercosur member and associated States have a residence route of their own, with a leaner document list. If your nationality qualifies, this is almost always the fastest path, and plenty of people apply on another ground without knowing this option existed.
