That's what I'm trying to find out about Liverpool. I don't get married till June, and my fiance visa doesn't expire till July. I just don't want to make an appointment at the last minute and find that they're booked for a month, meaning I don't get my appointment till after I've overstayed my visa. I'd rather make the appointment as soon as possible, even before I'm married, just so I have an appointment before the fiance visa expires, then deal with the marriage certificate and all the other paperwork after I'm married, but at least have the appointment scheduled. It seems to me that, based on the fact that the phones are always busy, there are loads of people making appointments.
