When you are doing any kind of business in a foreign country, it is always best to learn about the visa requirements. Every country has their own requirements when it comes to visas, and in some cases, you may not need to get a visa at all. When it comes to doing business in Brazil, in particular, whether or not you need a visa can depend on how much business you do in Brazil, how you do it and how much time you intend to spend in the country. In some cases, the amount of money you invest has an enormous impact on the kind of visa you do or do not need to get.
Investment: If your plan is to simply invest in a company in Brazil, you may not need a visa at all. After all, you will not be coming to the country, and only wish to be a part of business that is located in Brazil. On the other hand, if you want to be more involved in your investment, a visa may be required. People who are simply shareholders do not need a visa.
Hands on: If you plan to invest in a company that is located in Brazil, and you want to be there to do business in Brazil, things tend to change a bit. Your physical presence in the country could mean that you need to obtain a tourist visa or a limited business visa.
Relocate: If you plan to move your business to Brazil and take up residency, you may need to obtain a residency visa. This is the visa you get when you are frequently in the country.
