It was in ready status for a long time. Since October, but we were advised by our lawyer that we needed to wait for our invoice number to be sent to us. After receiving the information provided by others in this thread I learned I could call the NVC to receive the invoice number. After that, we submitted the DS-160 and our lawyer was able to set the appointment over the phone with the embassy directly. I don't know how they did that, but I do know that as of Friday the embassy stated that several days in early Feb are open for interviews, and that it was unclear when there would be other availability later this year.
