What are the final steps of spousal sponsorship?

[Charlamanderxxxx]

I have received Portal invite P1 and final decision, how long should it take to receive P2?

When my status will change from worker to permanent resident, do I need to change my SIN immediately or just before the expiry date of my temporary worker SIN?

For P2, it depends, could be several days, 2 weeks and I have seen some wait for over a month. You just have to provide the information they ask, make sure it is correct and wait and see!
