Hi guys,
You must be patient.The process is different from case to case and It depends of the officer who is dealing with your application.
This is my second application for PR because my first application was Canceled as incomplete because I forgot to add my original criminal record from my country and I added just the translation.
I got my ITA in 27 November and I submitted IN 15 December 2015 and after 5 days I had updated with medical passed
In my first application I got first updated after 3 weeks with medical passed and after another 4 weeks CIC. requested my IELTS test,that's 7 weeks after submitting my application.
After 2 days I got another updated,they received my Ielts and start Background check in progress.AFTER another 5 weeks I got my CANCELATION.
Depends of the officer who is processing your application.Some of the officer they don't require additional documents like:IELTS,CELPIC or ECA
Be patient and good look.
