What country are you applying in?Guess I'll just have to try and see what they say because I cant get there any other day and its pretty far away. I seen some der posts on here where they dis take them as a walk in , so it can't hurt to ask
I applied in the US, my appointment was in B'Ham, AL, and I got there a whopping two hours early-so I waited in my car. ROFLOL, the guard said I could have come in, and they would have done my biometrics the minute I went through the security check.
But he also said if I'd come on the wrong day they wouldn't have been able to do it-it HAS to be on the date of the appointment.
