When you say "Linked Application", what does that mean? We had a link to create PGP2024 application and that portal just says "submitted".
Is there any other portal link you are referring too ?
If you want to see the progress of your PGP application, it has to be linked to GCKey secure account. This is a separate account different from PR application portal where you had previously submitted your application.
You can create GCkey account with the link below:
https://www.canada.ca/en/immigration-refugees-citizenship/services/application/account.html
Once the account is created, you need to link your PGP application to it. Generally, you will require an
Application Number and/or
UCI (amongst other application’s details) which you must have gotten if IRCC had established a communication with you about your application.
For successful linking, provided information has to match with what was submitted. Note that you need not to be worried if you’re unable to link your application at this time. For some folks, it may take some time depending when they start processing your file.
Even if you’re unable to link the application; you will still receive all the necessary updates via email.
I hope that helps, good luck!
