How manys days in advance before an available UKVCAS appointment date

Hello Everyone,

Please if I try to book a UKVCAS appointment, how many days in advance do I have to try before I can get an available appointment date. Example if I need an appointment for a Monday 10th can I get one if I try the Friday before (7th).

for Super Priority appointment and any other priority levels pls.

Regards

Please how soon can I get a Super Priority appointment and any other priority levels appointment after submitting a FLR (m) extension application online please?

If I submit an application today, can I get an appointment slot the next day? Or would the next available slot be few days later?

Regards
