In my opinion the category 2 may take longer time than 1 because CIO needs to do verification about the job offer to insure that it is genuine and the employer is existent as well as they may have to look if the job offer requirments are matching with the knowledge and skills of the applicant.
whereas in category 1, they look only if the job description writen by applicant is matching the NOC accepted by CIC.
But if category 2 applicant accepted by CIO, I think the process time will be shorter than category 1 applicatn and the rate of successful is higher.
what do you think guys? please share your opinions
