So, one is an online update of passport number which is not a renewal. You need not worry about it. Just travel. The other one which is a physical renewal is a problem.New passport on crossing age 20 so I need to wait for the new OCI card. Thats why im wondering if i should just get an entry visa at this point.
Even for the minor passport update online - it says still processing rather than completed but I have more hope for that one being fine.
We have only two cases of such renewals in the tracker, one took 30 days from Ack to get processed compared 21-22 days for fresh OCI, other is waiting. If you search for similar cases in the past you will see most have taken longer than fresh OCI. I think you need to apply for entry visa.
That said, you will have to hurry for entry visa and apply by walk-in with or without appointment -- looks too late for mailing in.
