I currently teach in Brazil, and am vacationing out of Brazil. The visa in my passport expired today, but before I left Brazil I went to the police federal and renewed my paperwork. The new card wasn't ready before I left, but I have the slip of paper protocol saying the expired RNE is valid until the new one is published. Will this be acceptable to get on a plane to Brazil in the US? I talked to Delta and the agent said it was okay, but check with TSA. I have had no luck in contacting TSA. Any advice or answers? Thanks!
