My wife and I flew into Jurauz about 1 week before her interview so we had time to get the Interview letter from the consulate an do her medical appointments.
My wifes interview was early in the morning, I belive the letter stated 8:00am.
We never did recieve the interview invitation letter, and so we asked for it at the consulte window the day after we arrived. We needed this for her medical exam as well.
My wife entered the consulte asap in the morning of her interview and was back at the hotel around 930am. They asked her a few simple questions..
Then told her congratulations your visa is approved and gave her a green slip on how to track the visa, although We collected it at the consulates applicant processing center the next friday.
Oddly they ddint collect any documents from her other than her passport. It was almost as if they decided to approve the visa prior to the interview.
