Call for an appointment with the representative from the SSA office, but they should have asked you whether you need an ASL interpreter or not. It's ADA law to have an ASL interpreter to be presented to be there. The SSA office should know better than that. Or you can bring one of your family members with you as witness. Never, never, never go there alone because they trick you and also because there are misunderstandings between you and the representative. I have seen that often.
Again, tell them that you are requesting for an ASL interpreter and I wish you the best luck!
