I have no clue whats happening, I booked an appointment at US Embassy Kolkata, India for my H1B stamping. The site takes me to a page where it says "Please click on each link to download interview letter" but there is no link on the page to download. I have an appointment in few days and I am not sure what to do. It is mandatory to carry the appointment letter at the embassy and it is driving me crazy as google does not help too. I hope someone can help me on this forum.
