Honestly speaking the treatment for provincial nominees is not too fair. I too have pre arrival service letter since November the whole process started in 2017. Well after pre arrival letter has been issued then background check and co will commence until they are satisfied they will not issue ppr. It is very very rare to be rejected after medical or pre arrival or pay ment of rprf but it can happen if their is something terrible in the background check or so. Also most third world country and the likes don't have good police record for confirmation and proper check. In all let us hope against all hope in the midst of this corona virus. Some are saying this is not the best time to travel but we put our hope in God. If I have my ppr now ready to move as soon as I have copr but as it is everywhere is lock down but ircc still working from home. Some still receive ITA during this lock down. God will grant us the desires of our heart
