For Russian citizens, a visa to Brazil is not required, and accordingly there is nowhere to provide an invitation from a resident of the country.

But upon arrival you can ask for a voucher, for example, at a hotel, although in my memory this was not, but in the migration card you specify the address where you plan to stay in Brazil. Also, you may be asked if you have enough money with you, but with everyone now using credit cards, no one can check the amount of money, and they may ask for a return ticket, but that's not necessary. ±​​$ br >

The question is not quite clear. If you are not a citizen of Russia, and the period of your trip exceeds 90 days, it is better to clarify at the Consulate of Brazil.

I hope the following information will be useful:

Embassy of the Federal Republic of Brazil in Moscow - $ Address: 121029, Moscow, ul. B. Nikitskaya, 54 Phone: +7 (495) 363-0366, the consular department +7 (495) 363-0369 E-mail: brasrus@brasemb.ru

The Consular Section of the Embassy of Brazil in Moscow informs that on June 7, 2010 the Agreement between the Government of the Russian Federation and the Government of the Federative Republic of Brazil on the waiver of visa requirements for short-term trips of citizens of the Russian Federation and citizens of the Federative Republic of Brazil entered into force.

Citizens of Brazil and Russia who hold valid national passports are able to enter, leave, follow transit and stay on the territory of Russia (citizens of Brazil) and in Brazil (citizens of Russia) for ninety (90) days for each period of one hundred and eighty (180 ) days, counting from the date of the first entry, without obtaining a visa.

For citizens of Russia to enter Brazil, you need a passport, the expiration date of which expires not less than 6 months from the date of entry into the country.
