Unfortunately, no relevant information is found.
I want to know how to make my request be reviewed by someone else, as a second opinion?
For a second opinion or a higher-lever review, you need to download the VA form 20-0996: Higher-level review and fill it.
This is more about evidence. We didn't have the evidence we needed before, so my case was decided this way because we couldn't provide it. We've finally found it. Can I include it in the case ?
