@phere, I am also facing with the same issue. Did you find out any solution to get it done?
The only way i know is to register it at a place of residence with POA holder’s address proof.
We have done it ourselves in Delhi and used it to buy property in Haryana. It works.
I am trying to get power of attorney attested from Indian embassy. How do I reach out to Indian consulate in SFO. I tried calling but couldn’t connect. Is there an email?
It is possible that WFO embassy is not monitoring the calls due to Coronavirus.
