Is it possible to get a visa very quickly?

Normally, you can get your visa in 4 working days after your submission, and you can apply to use the 3-working day express service by paying an extra fee of 15 pounds. But you have to make sure that you submitted all the necessary documents. Thus, I advise you contact the visa center directly to get the accurate info. by call: 0207 710 6000 first, considering you are under so tight schedule.
