I do not think IRCC guys handle our applications randomly, they have their own rules:
1. Applicants who are in Canada (mainly CEC/PNP) with their dependents are being processed and finalized.
2. Applicants who are outside Canada (mainly FSW-outland/PNP-outland) with their dependents are being processed and finalized.
3. BUT, applicants who are in Canada (CEC/PNP/FSW-inland) with dependents outside Canada are not being processed or being finalized.
In a word, such applications are suspended without any deadline.
