Finally, I received the COPR last week, and waiting to receive my PR card. Like many other applicants I was worried about my application (Express entry-CEC, July 2020) with non-accompanying spouse who lives with me in Canada. Initially I thought I would tell them low CRS score is the main reason for my non-accompanying spouse application. At the time of application, I made a LOE saying that my spouse is not interested to become PR during this COVID situation. I showed this as the main reason why I am applying with non-accompanying spouse.
It is NOT mandatory for your spouse to apply for PR with you. It's your spouse choice, and that's how you should convince VO. Remember, even though your spouse is not accompanying, you both must submit police clearance certificates, biometrics and medicals.
Currently, I am working on my spousal sponsorship PR, and I don't know how long it's gonna take.
Good luck guys.
