Hi Shaheenaz,
yeah, took 8 months, same as Shiny.
Not sure what you mean by AOR. I just saw on e-cas, 'we have recieved **** ***** application for permanent residence on March 10th, 2011.' It should show the same on your e-cas if and when Singapore received.
edit. I(or my wife) didn't receive any letter or email stating that Singapore received my wifes application. I only saw this on my e-cas.
Sry, not sure either about what you mean 'is there any way out'? I'd assume you can always withdraw yours or your spouses application if that's what you mean.
