Hi! I'm in a similar situation, I submitted my application on 23 September and have uploaded my documents to UKVAS (but not clicked the scary 'Submit' button there yet). At the time I applied, I was told to expect an email telling me to book an appointment:
'Please continue with your registration and we will contact you, and update the website, when appointments are available for you to book. Until then, whilst the re-opened sites will appear on the website, you will not be able to find or book an appointment.'
I've not received an email, but now I see on the UKVAS website that anyone who submitted on or after 19 September should book an appointment upon registering:
'We are delighted to announce that our normal UKVCAS service has resumed. This means that UKVCAS customers (except T4 students) can book an appointment at a UKVCAS Service Point as soon as they register with us and no longer need to wait to receive an invitation email. This includes customers who registered on or after 19 September 2020.'
...but there's no appointments showing at all anywhere near me, paid or free. Should I just keep waiting and checking the website for appointments?
