Now applicants from April are getting AoR.
So we can assume the AoR can be expected as follows:
April -> in October
May -> in November
June -> in December
July -> in January
And so on...
Approximately 6 -7 months time for AoR.
That’s the reason why IRCC increased the processing time for PB applications to 21 months. It might lead to 24 Months.
