Hi Oliseh, I understand how much you are getting nervous, actually you need to be careful and cautious about everything, but take it easy!! KCC will end up giving all visa numbers to DV2010 applicants soon, perhaps in a couple of days. First of all, please do your very best to reach a person in KCC until you have confidence that KCC would give your interview date. Second, don't worry about Japanese police cert. All of Japanese police cert are sealed and do not open it. An embassy officer will open it at your interview. From what I read in this forum, police cert from other countries is sometimes not sealed and in this case you can open it to make sure that it is truly yours. Same thing to medical exam, do not open it.
