You can file a civil suit in a federal district court; which is the last level of the appeals process.
Also, what if I apply for both Supplemental Security Income (SSI) and civil suit in a federal district court?
You can now file for Supplemental Security Income SSI online but only if you meet certain requirements
By the way, do you know about the request for the child's disability report, can I complete the request online? or should I go to an office?
