Ohhh you have all my sympathy and support and admiration!
The hurdles we had to jump to allow an American girl to spend a year in Spain a nanny, taking classes at the university -- it was surreal. I'm amazed that we persisted. For you to get a Venezualan girl to Brazil shouldn't be that hard, but as you say, those bureacrats love to torture anyone they have power over. And a piece of paper has a ridiculous amount of power. GOOD LUCK getting that paperwork done and that daughter situated in college!!!
