FLR is basically a formality, it's really just a visa extension, so don't worry about any issues. As mentioned, they currently have a backlog that's the only reason for the delay. For those that have the extra £300 you can have it done the same day
Hi Keith
Any idea why there is a backlog and how big the pile is?
Just wondering where you read this info and if it had any other useful nuggets as I'm going to need my passport soon.
