From what I have read, NDVO do accept it if u have legitimate reason for not submitting the passport... You should write them a letter and attach your passport request explaining why its not possible for you to submit the passport now.. So you will get your second passport request thru phone or email at the final stage of your application... Once again, this is something I read in this forum.. There is no official confirmation for this... If I were you, I would give CIC a call or email them before doin anything...
