No, no appointment needed. You must be in line or have a pager or number before 3 pm.
No, not right now. You just need to show up early. Get a digital #, if they are extremely busy. Then you wait until your # is called or buzzed. Also, you cannot leave or you will loose your place. So take someone with you that has some time to spare. If it's cold take separate cars so that only one of you can leave to eat/drink/bathroom break. The other must stay on the primises with the digital #.
