Hi Tozo, where did you get the info about the date? I tried the phone service several times and all I got was "your app was received on Nov 2010, acknowledge letter sent on Dec 2010" and that's it.
The other question for you is have your non-accompanying dependents' ecas ever changed?
My son's ecas has kept changing every month but nothing really new sometimes and it confused me. Like just now, I received an Ecas updated that showing that my son's "medical received" which has showed on the Ecas a month ago. The other change is "we started processing your (my son) app on Nov 2011" is disappeared now from my son's ecas but I can see it on my bf (the sponsor)'s ecas now. It seems like CIC is moving the info from here to there and then moving back....a little drives me nuts, I hope I know what they're doing now....
