You can apply for Social Security Disability in three ways. You can apply online at WWW.SocialSecurity.Gov, you can call 800-772-1213, or you can go to a local Social Security office in person. You will need to provide documents, such as a birth certificate, tax forms, and medical records, or Social Security will need to get them. You will also need to schedule an in-person or phone interview, which will probably take about an hour. From the time you apply to the time you get accepted or denied can take anywhere from a couple of months to eight months. If you are denied, you have a right to request a hearing.
