L2 VISA holder with expired VISA in India without an I 797

I have a valid I 797 for my L1A VISA, which i need to get stamped… My wife did not get her I797 and had to travel to India due to family reasons… As of today, there are no VISA interview appointments available in any of the 5 Indian consulates for the foreseeable future… .Dropbox is available but since my wife does not have her I797 i am not sure if she will be approved in Dropbox … Any pointers from anyone in the group will be a great help. Thanks

Did you get a reply on this from someone? We are in a similar situation.
