Passport renewal during green card process

Posting on behalf of someone:
"I hold a conditional PR (temp GC) expiring end-April 2023. The I-751 form to remove the temporary PR condition will be filed 90 days before expiration ie end-Jan 2023. My Indian passport expires Nov 2023 & I am now eligible to apply for its renewal (1-year in advance).

Question: Should I get my Indian passport renewed before submitting I-751 or after? Given the I-751 processing time is 12-18 months, my passport will expire before full PR is granted. Please suggest"

Either options are fine. Even if you renew after applying I-751, it doesn’t impact your application.
