Hey, me again. As far as I know SSD/I and VA comp do not cancel each other out. So…in your case, it may well make it easier. Other Vets have used their SSD to show they can’t work and used that as the keystone for UI or P&T or something of that nature.
My twin brother got his SSD before being awarded UI. So…you should be just fine with it. I wish you all the best, times 100 and again.
