I was approved by otr but I was 55 when I was approved, took one year to receive my Ssdi, I also had close to a a 40 year work record also. I Los meet a blue book listing 4.12b. So if you don't meet a listing and are young and have a short work record, it's hard to get a otr. If you are young the all wants to see you face to face. A senior attorney at the odar approved me.
