Thank you for that input! Just wanted to add that after our vacation out of Canada in Dec, I will be back and my husband will be staying in Canada with me for 5months then travel for 2 weeks, come back again for 5months, out for 2 weeks. So basically he will spend at least 10.5 months out of 12 in 2022 in Canada. Do you still think Inland PR sponsorship is not possible?If he'll need to travel back and forth, outland is better. If he does outland, though, cannot apply for open work permit.
Generally no need to hire a lawyer - it's intimidating at first but manageable.
Apart from that had other questions:
1. Once we start the application inland/outland, can I (Sponsor) leave Canada for few months? Is there a limit of days I can go out of Canada?
2. Does the Spousal PR application get any points based on work experience of the person being sponsored?
3. Is there a way to share details of any immigration law firm that you or someone you know have had a good experience with on this?
