My PR application was refused due to missing job duties in letter of employment submitted for current employment. I am trying to get an updated letter of employment from my employer with job duties mentioned on it and will submit a new application after receiving ITA in next draw (hopefully). My previous application went straight to IP2 after medical passed and on the day of refusal, my background check status was changed to completed. Does IRCC refers to previous application for some reports like background check or my new application will go through the whole process again? If they consider reports from previous application, this may reduce the processing times significantly. Please advise.
