This might be not possible in normal scenario, but we are not normal now, we are COVID victim :).
I had visa till July 28th, I already renew my visa and got I-797 till 2025.
I am planing to go for renew stamp to India in June. I am searching for dates to dropbox in Mumbai consulate. I was trying from 2 weeks, but no success.
Now the real problem, in case, I go to India, and we don't get the appointment date for the drop box. If we come back on our tourist visa (B1/B2, which is valid till 2024), then, Can I legally work as I have valid I-797 till 2025 ?
If we come on B1/B2 visa, we have to go back before 6 months, but at that time, I think we might get the dates.
