I'm so sorry that you and your husband are going through this.
I know the torture of waiting so long. It was over 3 years after I first applied for SSD (two denials) before I had my hearing (I just found out I was approved
). After I got the letter from my attorney that they needed some additional paper work before the hearing, it was a few months before the hearing was actually scheduled.
Good luck and hopefully his will be scheduled soon.
