Pandemic - New B2 visa for parents

Hello,

I am in an urgent need to get my parent to the USA from India in B2 visa. Currently there are no consulates open for regular appointments in this pandemic testing period. But what are the options I got to expedite the visa processing? Also, Please help me with any useful links, twitter, facebook handles or news feed about visa processing update.

Thanks in advance.

Any help is much appreciated.
