@ Sheen Services,
Thanks for your reply. The agency in Chennai, India asked me company stamping in my experience certificate which i had arranged. Then they asked my original degree certificate, bonafide, consolidated mark sheet as a supporting document. i had couriered to them. Now they are asking a letter from the present company (employment confirmation stating NOC or reason for attestation) which should be attested by MOFA Qatar. MOFA Qatar told me to get Qatar chamber. Is this complicated process required by Qatar Embassy..? other agencies in India how they are getting attestation, i dont know...
