The Verdict: Not eligible
The age limit is 30 (34 for South Korea), with no discretion, so this route is closed to you. Look at the digital nomad route, which has no age limit.
Remote work for a foreign employer or clients gives residence on US$1,500 a month or US$18,000 in savings. It runs a year and is renewable.
Other routes ignore age too: a job offer from a Brazilian employer, a pension of US$2,000 a month, investment, or a Brazilian spouse or partner. If a parent or grandparent was Brazilian, citizenship by descent has no age limit.
