Once u walk in, u check in with the person up front, let them know the reason for your visit, they ask for your ssn and pic id, your then given a half piece of paper and a #, fill it out, return it back to the person, then your asked to be seated until your # is called. Your wait really isn't that long.
To go in and register - 5 min. To fall in line - 5 min to 60 min. Better go in early.
