An appointment is not needed. But, if able to make one, it isn't a bad idea to do so. Each 'customer' could take anywhere between 10-30min, dependent upon their individual needs. There are multiple stations, but if there is a large amount of people before you, then the wait can be extensive. *Note - there is priority for military personnel in uniform.
