Energency H4 visa processing during covid

My husband is in the US and I’m in India. Due to covid, I was unable to get an appointment and process my H4 visa. Am I eligible for the emergency appointments/visa to have my H4 processed and for me to travel to the US? Thanks

Hi Meghana,
You are eligible to apply under the emergency appointment, go ahead and apply

Thanks for your quick reply! Can you please share the guidelines for eligibility for emergency visas?
Also how would the previous be different any ideas??
