I would recommend to make a reservation and register online, it makes the process a whole lot easier to deal with, plus you can schedule the hours that are more convenient to you! Also, as long as you have a vaid I.D. card, you shouldnt have to worry, I think! Lol
As long as you have an ID you can just walk in. They open at 11 and i would recommend you go as close to that time. I can sometimes get quite busy.
They accept walk-ins. As long as you have an identification card and are at least 18 years old it's okay.
Have a valid passport with you. Usually better to call ahead, but you can walk in. If it is busy. You may just have to sit and wait for a lane to open up.
