I am planning to extend my stay in Brazil for more than 90 days (I am a UK citizen). Ideally, I would like to do this next week. I am not sure what to do - i.e if I need to pay a fee, what documents I need to take with me, etc (I have not got an actual copy of my return ticket as I have an "e ticket"). I know that I need to go to the Policia Federal (I am in Rio) though I have no idea where that is nor what hours they are open for tourist permit extensions.
Thanks for any help,
