Thanks for your response. It did include an application number and UCI but I assumed those were for my application to sponsor my wife and not for my wifes application for PR as the email stated "This confirms that your application to sponsor a member of the family class has been received by CIC on behalf of xxxx (my wife) " She has a UCI from when she was approved for a working holiday visa and this is how we linked her application. The file number to her linked application and the one in my email were different hence why I believe that this email was in regards to my application to sponsor her. Thanks for the help!You refer to the "Sponsorship application being processed email" - that is AOR. Did it include your application number and UCI?
