So I passed the interview and got the visa in my passport and the brown packet. So my question is what next? I will fly into the US, and once I reach customs I just give them the passport and brown packet right? Then do the customs people just let me through, do i get my green card....etc. anybody with this experience would be greatly appreciated. Also in the interview I had to sign a selective service notification, and it says within 30 days of entering the US I have to register or something? Anyone knows how this is done? Anything else I should know? Because curiously the packet's only instructions is to bring chest x-rays and not how to proceed and/or when to receive the green card. Thanks a lot!
