The Verdict: Not eligible
This route needs a Brazilian spouse or partner, so it is closed to you. If your partner holds Brazilian residence you can join them through family reunion; otherwise look at the skilled, digital nomad or investment routes.
Family reunion with a foreign resident gives you residence, but not the one-year route to citizenship. You would naturalise after four years like anyone else.
Other routes into residence: remote work for a foreign employer, a pension paid from abroad, investment, a job offer, and for most South American nationals a residence agreement with no job offer needed.
If a parent or grandparent of yours was Brazilian, take the citizenship by descent quiz first: Brazil has no generational limit.
