Because space at clinics is limited, signing up in advanced is strongly encouraged. Those who do not schedule their visit in advance may be able to walk in on the day of the clinic during set hours if that option is offered. Some clinics do not have the walk-in option due to space or other limitations. Check details for the clinic you are interested in attending. Please note that those who walk in may have to wait longer than those with pre-scheduled visits depending on staff and attorney availability at the clinics.
