The Verdict: Not eligible
Brazil has no working holiday agreement with your country, so this route is closed. If you can work remotely for clients abroad, look at the digital nomad route instead.
The visa exists only where the other country grants Brazilians the same benefit. Agreements are in force with Germany, Australia, South Korea, France and New Zealand, and one with Japan opens on 1 December 2026.
If you hold one of those nationalities too, use it. Otherwise: remote work at US$1,500 a month or US$18,000 in savings, with no age limit; and for most South American nationals a residence agreement with no job offer needed.
