I have done a 3-year BHM from IHM Hyderabad (NCHMCT) which was collaborated with IGNOU. I was told attestation can be done if IGNOU can confirm to the Saudi govt that the course was a 3 year full-time and classroom-based course. Can someone tell me what’s the process?

I have done a 3-year BSc in Hospitality and Hotel admin from IHM Hyderabad (NCHMCT) which was collaborated with IGNOU. I now have a job opportunity from Saudi but unable to attest my degree certificate as the Saudi govt doesn’t approve open university degrees. I was told attestation can be done if IGNOU can confirm to the Saudi govt that the course was a 3 year fulltime and classroom-based course. Can someone tell me what’s the process like here? Any suggestions here will greatly help!
