It seems that all applicatons which they had asked to provied additional documents last feb and march have all the same situation, the controller just recieve your email and when he find that your file is active queue with an officer , he simply forward that informationor email to him ,, that had been the case in my GCmsFeb 14th ,2017
A friend of mine paid the RPRF in march without being asked to do so his receipt had been linked to his account after a month ( in april )
Though both of us are Quebec skilled worker
Hope we hear some good news soon
