My application for parents was submitted in 2016. In February 2017, I received the medical exam request and submitted immediately. It shows "medical exam result received" on CIC website since March. On December 15, I received the medical exam forms from CIC again for both of my parents. At the same time, I also received "pre-arrival service" email. I was so confused about the reason of the second medical exam request. Did anyone else experience same situation before?
