Hey,
I also applied for my mother online & once I did post biometrics I got in total 3 mails from vfs.
You may get one more mail saying it is sent to ircc for processing.
At least I got it.
I am now waiting ......
Next from what I have understood, two things can happen ...
1) Passport will be requested and then a mail might come saying the envelope has been dispatched back to vfs .
2)Else no passport request and just a mail saying the envelope has been dispatched back to vfs and please collect it.
Processing times might vary.Stay positive.
All the best !
@gloryksingh - can probably help us ...
