Question on I-797and VISA renewal. Do I need to be in India?

[Affyn]

Hi,

My H1B petition will expire on 2nd September 2020 and my VISA was approved today. I have to collect my passport in few days.

Basically I will have to renew both. My question is -

Am I suppose to be in India for renewal of Petition and VISA?
How do I plan so that I don't have to return to India for renewal of either of it?

Thanks for the help.
