Hello, I am confused why I cant book those not highlighted dates. Unfortunately, the date I prefer to get appointment is not highlighted. I am worried now don't know what to do. Please help.....! thank you in advance...
If you want to book a date that is not highlighted in the website, why not try to call the UKVACS call center and ask them if your preferred date is available. As what islander said, if you do it online you can only select from the dates highlighted.
