Waiting time for appointments on the day - US Embassy London

Hi guys

I was wondering if someone knew roughly how many hours it takes to get through your interview at the US Embassy in London? I wish to apply for a B1/B2 visa there soon and just wanted to know how long I can expect to spend at the embassy.

Thanks

I think the guidance states that you should expect to spend between 2-3 hours at the embassy. My personal experience matched that when I applied a few years ago.

Most of that is spent queuing and waiting for your number to be called for fingerprints and then the interview, which only lasts a few minutes.
