Congratulations! As mentioned by Nekeol make a covering letter addressing the immigration officer with your File Number on it
and mention that you are attaching your medical, RPRF(file No. on the back of the Demand Draft), Photo copy of the medical receipt and photos. You may have to send 2 photos of each family member and kindly note that you have to write down the name on the back of only one photo with a soft pen so that the pen marks do not appear on the front part of the photo. Hope it will help
. I pray for a very successful ending for all the applicants....
