Did your job duties match the selected NOC? Did the letter have the required items as per CIC? If your letter is fine and your NOC is correct then there should be nothing to worry about. If you want, you can post the case analyst notes (of course remove the personal details) here so others can provide an insight as to the possible reason for your RR.Thank you for your reply.
I have received notes and it does not state the reason for RR. Case analyst just mentioned these two words (Review required) against my Foreign experience documents. Job responsibilities are mentioned in the letter I had submitted, so not sure for exact reason for RR. Also Foreign experience points mentioned is "0". i am bit worried now as this brings down the overall CRS.
