Hi Neeti,
If I recall, your parents' visa has already expired, correct? With VFS in India yet to open as well as New Delhi Visa Office still not fully functional, I am assuming their CoPR extension is yet to be initiated? FYI - my Mom's CoPR expired. Hyderabad VFS does not state any expected opening date on their website. Are your parents in Delhi or need to travel domestic - because that is another issue for us! Domestic flights are sparse and we need to plan connection with the Air India repatriation flights. Happy to exchange notes on progress, if you like.
Regards
Nav
