Interview was for IR5.
when we went for the Medical - 1 week before the interview, they handed us a paper saying, "DO NOT go for he interview."
after more tests were done - 2 months later - the clinic sent us the medical approval and said they have sent it to the consulate, and you will get a new interview appointment within 7-8 days.
it's been 2+ weeks now - upon following up with the clinic - they said we just have to wait for the consulate to schedule and they cannot do anything about it.
