My application was also sent on April 9th , received on April 12th (as per Canada Post tracking) and no news so far.
Any advice on when we can contact CIC to ask for information?
"...If it has been more than six weeks longer than the time shown since you applied, and you need more information concerning the status of your application, use the Case Specific Enquiry form. .."
More than six weeks after the date in CIC web page (Check application processing times) shows application received in April 11th are being processed (date which application was received as per courier tracking)?
