yes... you need an attested copy of educational certificate. you dont have to give original attested, a xerox copy of the attested certiifcate will do. also need following documents:

Police Clearence Certificate (PCC) from your embassy (Original)

Letter in arabic from the new company. (Oroginal)

NOC from current sponsor.(Copy)

Blue form from Immigration (copy)

Bank card to pay Qr. 10 fees

Both the educational certificate and PCC must be attested by Qatar Ministry of Interior.
