I saw on couple of comments that if your status on the CIC website for PR application indciates 'In Process' that means medical request is coming soon? is that true?
It doesn't mean anything other than your application is being processed. It passed the completeness review, you should have received your AOR, and the file has been transferred to the visa office (presumably CPP-Ottawa). And now you wait
Seriously, your medical request might come soon, it might not. It doesn't really mean anything either way.
