This is a long proces, you will need lots of patience to get through it. Just look at my situation, they informed us in an email reply that Re-medical letter was sent out on Feb 18th, 2012. We didn't get it, so we emailed and faxed them quite a few times and asked them to Re-send the letters but they have not send it yet. Its been two months since and a total of 16 months so far since we applied but our case is stuck due to a mistake by CHC-Islamabad employee who forgot to send the medical request and as a result we are suffering even more. I am just giving you my example to prepare for the worst, other than that Allah knows the best and has a plan for everyone.
