No, you can only attend if you have a pre determined appointment and walk ins are not allowed
You need to setup an appointment after you call them, if you have an emergency explain the situation and bring with you the proof of your emergency (documents) and if you wanna speed up the process try to contact your congressman or woman, explain the emergency situation and they should help you out to get an earlier appointment.
