Struck in India - waiting for Visa Processing

Hi Anil,
Due to family reason, I came to India, chennai. I am under H1B with I797 approved until Dec 31, 2021. To return back to US, I need to get my visa stamped. Considering the current situation, when can you expect US to restart immigration in india so that I can get Visa stamped and travel back to US. Any risk you foresee for my approved I797 due to this situation? Please reply this is very urgent for my situation here. My priority date is Eb2, India, May 2010. Please share your thoughts and thanks a lot.

At this time, there is no information about when US embassy might reopen.

The best guess would be around June first week. Do also plan for heavy load and long waiting time as lot of people are are waiting to book appointments.
