I was awarded IU yesterday. I've read different answers so I'm looking for anyone with experience. I filed for IU as soon as I was discharged from AD. This is my first go around and I was approved after waiting 8 months. Will I receive backpay from the date of discharge/filing? I know for ratings it'll backdate to the date of discharge if it's within a year's time of filing a claim but is it the same for IU? I've different answers such as the VA will backdate it to the date of approval not filed. Any insight? Thanks!
