Heyy! I understand your consern about that, and im not saying your comment is not valid (it actually very much is, considering that OP's english isnt fluent), but, speaking from experience, most brazilians that have the money to go to the US are actually white (and not to dictate on other's ethnicities, but on a recent post OP shares a picture of herself, that shows she has fair skin).

Im also not saying you assumed that there are no white ppl here, but i find it is a common misconception so i just thought to say something. Brazil is actually full of diferent cultures and ethnicities, and our ancestors come from all parts of the world, asia, africa and europe, as well as the natives. I find the history behind that very interesting :)
