. We applied by ourselves. Before applying, we were informed that the average processing times for NDVO applications was from 10 to 12 months. It has still not sunk in that we have received PPR. I feel blessed & grateful.

Good luck to you. I wish you all the best. Hoping everyone's applications gets processed smoothly without any hiccups.
