Thanks.
What I actually meant to ask was -
1. Should I expect a DM for PA soon now that I have a pre arrival letter?
(I checked the tracking sheet and see no progress for people after pre arrival letter)
2. Can I expect that IRCC will not be asking for any documentation until complete processing of the application? Now that they have issued a pre arrival letter?
3. Is there a chance that I might receive a bio metrics request after pre arrival letter?
