Check this out:Don't worry my friend . At least you you can check application status . In my case I received invitation from IRCC in April 2019. I forward that email to my friend , as he got his immigration consultant license and wanted to handle my case . With first few errors and delays , he told me that he submitted the application vie mail. Now , I believe IRCC is slow due to covid and he don't have any update on it.
I created an account on IRCC and tried to add filled application via using last name / birthdate/passport info/ also tried that B1D****-19 reference number I got in invitation email. That was everything I had and I could't add that filled application under my IRCC account . Please help me here . All I want to add my parents sponsor application under my IRCC account . Ty!
