Thank you! Just very quick update.
I just got notification email from the CIC website. When I checked it I got one message. They requested for my medical exam because my medical exam already expired two months ago. Then after that I got another email notification again from the CIC website and when I checked it was a letter from the embassy. In that letter its said that I have to complete the medical exam and submit police certificate and send it to the Canada Embassy in Singapore. This is the letter that I got :
This refers to your application for permanent residence in Canada. Please follow the steps below
so that we can continue processing your application.
