The Verdict: Not eligible
You cannot naturalise from outside Brazil, because the clock runs only on residence there. Start with a residence permit: our skilled, digital nomad, retirement, investment and marriage quizzes cover the main routes.
Brazil has more ways into residence than most countries: remote work for a foreign employer, a pension paid from abroad, investment, a job offer, a Brazilian spouse or partner, and for most South American nationals a residence agreement with no job offer needed.
The route you choose decides the wait. Ordinary naturalisation takes four years of residence; one year is enough with a Brazilian spouse, partner or child, or the nationality of a Portuguese-speaking country.
If a parent or grandparent was Brazilian, take the citizenship by descent quiz first: you may need no residence at all.
