Experience certificate attestation by Saudi Embassy New Delhi

Hi All,

I got a offer in Saudi , currently working in India. I started Work visa process with help of agency in New Delhi. Currently my B.Tech degree is sent for attestation to Saudi Embassy Delhi. My visa consultant is saying after this Experience certificate also  needs to attested by Saudi Embassy before submitting for Visa Stamping. Is this step needed? I don't find anywhere saying Experience attestation is needed for visa stamping.

How did u get attestation for experience certificate?

Yes it's needed
