Have you ever called them to find out when they will start the next step of processing your application?There could be a chance that it will be returned since IRCC tells you not to post-date applications. The following is on their website:
"Note: Your application will be returned to you if it is:
ECAS also lists both the date your application arrives at the IRCC and the date they issue the AOR. On my ECAS, it states the following.
- not signed and dated
- dated more than 90 days before we receive it
- post-dated (dated into the future)"
"Citizenship
- We received your application for Canadian citizenship (grant of citizenship) on January 9, 2020.
- We sent you correspondence acknowledging receipt of your application(s), and a study book called Discover Canada on March 12, 2020."
My application was received on January 14, 2020 and I received my AOR on March 13, 2020 so, pretty close to yours. I hope we'll start to see some movement very soon though.
