If u submit new documents to NDVO/CIC it will take upto 15days to get processed into their system. U can expect PPR this month if no further documents r requested by NDVO.
All the best!
To my knowldege wat u get once the application is about to get approved is pre arrival services email. Some receive prearival email & PPR on same day.
U can expect PPR with in 3 weeks time after prearrival services email.
All the best!
