I received first PPR / Ready for Visa email in my inbox (the gmail one) on May 25, 2017. I sent my passport along with other mentioned things through VFS to CIC Islamabad Office on June 19, 2017. Through VFS tracking, it was confirmed that my passport has been delivered to CIC Islamabad on June 20, 2017.
No further change in status observed till August 8, 2017, when I received an email that myCIC account has been updated. I checked myCIC account and I found that there is another "Ready for Visa" email in it. The contents are the same (including sending passport to Islamabad Office) however, the date of the letter is different (i.e. August 8, 2017).
I have carefully checked if the earlier email address from which the earlier email was sent was an official one. It is indeed an official email address of CIC.
Now my passport is already with CIC Islamabad Office from June 20, 2017. Any suggestions on what should I do? I have already sent them an email (the address that was mentioned on the PPR email).
