how do they look to see if I got the VAs assistance that they should have given me?
If you requested a Higher-Level Review or Board Appeal, Duty to Assist doesn’t apply. However, the reviewer or judge will look at whether VA met its Duty to Assist during your initial claim or Supplemental Claim
can you tell me about the Veterans Law Judge review ?
You have the option to request a hearing with a judge. A video conference hearing will take place at a VA location near you.
