The Verdict: Not eligible
Brazil does not sell citizenship, so there is nothing to apply for. If you would live in Brazil, look at residence by investment, which leads to naturalisation after four years.
No donation, fund or contribution produces a Brazilian passport, and you should not pay anyone who says otherwise.
Residence by investment is real: R$500,000 into a Brazilian company (R$150,000 for innovation or research), or R$1,000,000 in urban property (R$700,000 in the North and Northeast).
The passport then comes by naturalisation after four years of actually living there, or one year with a Brazilian spouse, partner or child or a Portuguese-speaking nationality. If you want a second passport without moving, Brazil is the wrong country.
