I have been contacting IRCC regarding my Wife's application to sponsor her parents. Unfortunately, Although I submitted a rep. form, every time I called they were telling me that the file is not open yet so they can't access the Rep. form and although I am a co signer , they can not give me information regarding the file. I decided to call with my wife this morning, after verifying my wife's identity, I asked them what is going on?! and after putting me on hold for 3 minutes, the agent comes back telling me that the file has been approved for completeness in December 2019 but no file was created. He said he will email the officer and ask what is happening with the file?! this just shows how the IRCC is so disorganized and there is no guideline for processing these applications.
Call IRCC till you get an answer to why your file is not being processed? they may just forget about your file. It is your right to know what is happening to your file and they are obligated to give you answers.
