The Verdict: Need More Info
Your record can cut naturalisation from four years to one, but the decision is discretionary. Collect evidence of recognition inside Brazil: awards, appointments, publications, press.
The law gives the one-year reduction to someone commended by professional, scientific or artistic capacity, or who has rendered or can render relevant service to Brazil. The justice ministry assesses it.
Brazilian-facing recognition carries more weight than general eminence.
Check simpler grounds first: four years of residence needs no assessment of merit, and a Brazilian spouse, partner or child gives the one-year reduction as of right.
