Current visa appointments

Can anyone please tell me why the consulates are closed for visa appointments currently? When can i expect it to be opened?

I Truly understand ur concern , Trump had passed an executive order in March 2020 , to stop giving any new visas , either immigrant or Non Immigrant, unless u don’t fall in that case , they have started processing visa on a chronological order , hopefully soon , my spouse is in the same Boat , waiting patiently, Good luck ,
