I just got my conditional approval as a UK citizen.
Oct 14 01:00 - Applied on gov.uk
Oct 14 22:15 - Got my access code
Oct 15 20:30 - completed application (had to check employer's phone number lol)
Oct 17 05:00 - conditional approval
I was expecting a few months, I don't have any travel to the US planned until March and even that isn't booked yet.
