ntasa...for CEID you need a Character Certificate from Your Embassy, further attested by Qatar Foreign Office and then submit it alongwith Passport Copy & a Photograph with a filled up form which can be obtained either from the CEID or any Typing Services Centre. They normally take 10 working days (2 Weeks). After two weeks, the PRO/Mandoob of your new employer would go & collect the Clearance Certicficate and then apply for the transfer of your visa in the Immigration...which may be done on the same day.

gildine23... You would always need an NOC from the sponsor once the visa is stamped on the passport. Without NOC, you cant come back to Qatar for two years.
