I will check out the July-Aug-Sep 2016 thread as that is a very good recommendation! Thanks.As per my understanding you are in the right direction but your UCI point confused me too. Did you check with anyone else ? You can put your query on July- Aug- September 2016 topic where most of the people have already received their PPR. Check with them if they have received the same letter. Let me know as well I am wrong.
Since the single PPR email sent to our principal applicant requested us to include all passports for principal applicant and any dependents, we mailed in it all yesterday. It seems highly illogical for a second PPR email to be sent with another passport request for our dependent, so I think we are good.
Oh,and my UCI point was just that only our principal applicant had the UCI number listed, not the dependent. That said, on our myCIC account, our application number lists both UCI numbers.
Thanks again!
