Thing is from my organization many people got thier PR with the same letter. So, i asked my HR to give the same letter. Everybody used the same NOC CODE, same JOB LETTER.I am not sure. Maybe ask your organization to help you out with preparing Job Letter matching with NOC code? Or call CIC and ask them about the same. Don't worry.
Your application will be viewed by the Main Visa Officer, if he/she approves it then you will receive PPR.
So, that's why I am not sure what I can do now.
