From what must be a press release:
... SSA recently released the eSignature/Upload Documents initiative nationwide. This end-to-end secure service allows customers to electronically submit some frequently used forms, such as appeal requests (SSA-501 and SSA-561) and waiver of overpayment recovery (SSA-632). Customers can also submit evidence, including the VA Disability Rating Verification, medical and school records, bank statements, tax forms and many more.
Social Security employees initiate the request by sending an email to customers with the required form. In turn, customers review the request, electronically complete, then sign the form (if a signature is required) and submit directly to SSA. ...
I guess they must be going nationwide for what had earlier just been an experiment in the Boston region. Why does this have to be initiated by a Social Security employee?
