My spouse went to the consulate without me (the petitioner) because I was already in the US. He said that there was a big line and officers asked to check his paperwork three times, including once while he was waiting in line outside in the rain. The interview wait was a couple hours. The interviewing officer asked a few basic questions and said everything looked good. They just hadn't received the medical results yet. The visa was issued 9 days later, but we didn't receive the news that his passport was ready for pickup until 2 weeks after the appointment. Don't forget to check the status updates on the CEAC site. We didn't realize they we could look there.
