The Verdict: Not eligible
Brazil has no global talent visa, so without a Brazilian institution behind you this route is closed. Look at the digital nomad route, which asks nothing about your profession.
Every talent route needs a Brazilian university, company or public body employing, hosting or backing you. Finding that counterparty comes first; the immigration follows.
Other routes: remote work for foreign clients at US$1,500 a month or US$18,000 in savings; investment from R$150,000 for an innovation or research business; and for most South American nationals a residence agreement.
Your record counts later: once you are resident, a commended professional, scientific or artistic record can cut naturalisation from four years to one.
