Super Visa application after eCOPR : Start Immediately or Wait?

[vkamath]

Hello Members,

I'd like to start the process of Super Visa for my parents. I have few questions as below

1. Do i need to wait some time like 6 months after I get my PR confirmation or can I start it as soon as I get my eCOPR
2. Can i start the super visa process after the eCOPR is generated or should i wait for my PR card?

Any suggestions will be helpful
