How to Contact LONDON VISA OFFICE and related questions

[cuccoo0]

Hi all
Please drop a couple of lines on the issue below

What happens when one sends the completed application to the VO

Shall they issue an AOR
Shall they issue a new file number
Shall one be corresponding to the VO using the B# mentioned in the email by CIO

The London visa office says that if you have some information to change dont do this untill we issue you a file number?What does this mean

More question sare coming but first these
regards
