I've already submitted my UK visa application, but have yet to receive the visa.
I need to book a flight a day or two before the 'intended date of arrival' that I've entered in my application.
My question is, if and when I get the visa, will the validity be from the date it was issued, or from the date of intended date of arrival I entered on my application.
In case it's from the intended date, then is it possible for me to arrive a day or two before that day, or will it create problems with the airport security?
