You don't need to make an appointment they are quite quick
I last visited around 2pm & only waited 15mins or so. It's like the DMV. You get a number & they call you, but alot quicker than DMV👍.
You might want to try the ssa web site and there's a lot info. And find the 1800 number to try to make an appointment.
