Your mother applied for PR as a live in caregiver and you are her dependent - correct?
If so, then you should post your questions to the Foreign Worker section of this forum since this is where all of the discussions are located for individuals going through the PR process as LCPs. The timelines you will experience will be similar to those others going through the LCP process will see. Your processing times won't be at all related to the processing times of those going through the PR process via Family Class.
