Gave my biometrics in London on Friday. It has to be the most dingy, depressing experience of the whole PR application process. Definitely book an appointment beforehand. I arrived half an hour before my appointment and was told to leave and come back no more than 15 minutes before! Walk up applications had a 2 hour waiting time estimate.
So I walked around the block a few times and went back with 15 minutes to go and was given a ticket with a number on it. Walk up to the 2nd floor waiting area which was a mix of pre-booked and walk up applicants. There was a screen with two lines of numbers, one for pre-booked, one for walk ups. All of the pre-booked were getting seen before the walk-ups started. There was only one person processing all applicants.
There were 6 pre-booked applicants waiting before me. Processing took around 5 minutes per applicant but between each one, 2 or 3 walk ups would interrupt and ask the processor questions which really delayed matters.
After 30 minutes, it was my time to give biometrics. I handed over my biometrics letter and passport, gave fingerprints and had my photo taken. That was it. For the whole time I was there, there was not a single smile, please or thank you. Reminded me of US immigration.
Glad it's over.
