One last question, is there a way to schedule an appointment so I can apply in a local office instead of online? The process confuses me.
Yes, you can also schedule an appointment with a local Social Security office to file an application. Call 1-800-772- 213 or TTY 1- 800-325-0778 from 7 a.m. to 7 p.m., Monday through Friday or contact your local Social Security office.
