I applied last Wednesday. I did email in after I submitted my application and was told 15 working days nut if extra documents is required the 15 days start again when submitted.
When they asked for accommodation booking did you provided a booking for your whole stay for your up and coming visit? Also bank statements did they ask for 3 months? If so how did you upload multiple documents or was the statement all in 1 file
there is an option when doing TDAC to enter VISA number but not compulsory to add to TDAC. I am entering and looking to obtain visa exempt upon arrival. What VISA did you get from London ? Previously I did use a TR visa and although they had it on their system upon arrival i still showed them a printed version. Immigration officer informed me due to length or stay and propose I don't need TR visa and I should just turn up and get visa exempt.
there is a QR code but I have drawn over it so it can't be compromised. My understanding is to show this to the immigration officer along with passport.
