I am leaving in 9 days for UK, to be married. I have been trying to find more info on applying for the FLR, but all I can find is that it's necessary to do it within the 6 month period on my visa. Do I HAVE to go to London to get it, or is there a form I can download to mail in with documents? If that 's possible, would it be less than 500 lbs? We don't have a certain time that we want to travel, I just know I have to have it. Thanks!
