I am a U.S. citizen filing for I-130 for my brother. He and his family currently live outside the U.S. Would his future interview be conducted in English? Would he be denied if he doesn't speak good English? What questions would they ask him? I know it takes 10-12 years, so his interview won't be occuring until then? Would it help if I fly back to join him for the interview? Many thanks for your kind reply. I would be very grateful.
