I have a CUE claim where I am asking for retro back to 1973. I have a lawyer. I would advise you to get one if you can since the VA will fight this claim of yours. I have been to the DRO,BVA, Court of Vet Appeals and back to the BVA on remand. It has taken almost 6 years. You may think your claim is obvious, but the VA will find fault with every part of it.
