It might be interesting for you to know after I landed on August 25th, my eCAS status changed to "Complete". Very randomly, I was checking my eCas again and surprisingly it had been changed to "Decision Made". I was surprised and closed the page. Two days later I received photo request email. From the date they received my photos ( Oct 16th ), I checked my eCAS status and it was again "Decision Made" until today. It is now changed to "Complete" again.
What I am trying to tell is that I guess most probably they are working on photos after Oct 6th. I will let you know my timeline as soon as I get any new updates anyway.
