Thank you my Dear Friends for your brainstorming!
I'm sure #2 is AOR 2 (
@alaria , I apologies for my typo, thanks
@JoshC corrected it)
= GCKey
#3 Warsaw started to work on my application (one business day before AOR2)
On the main page of ecas PA's status was "in process" since my first access to...
No related info in GCKey
#4 was a long investigation process
In reality, yes it correspond (as
@alaria wrote) to mail that I got on the 12th "This confirms that your application for permanent residence in Canada has been received by Immigration, Refugees and Citizenship Canada (IRCC) on YYYY/MM/DD"
Mail was send by Sydney, no actions required from our side. IRCC call center confirmed that that mail and line in ecas correspond to my file transfer to Warsaw. (their logic not clear for me, but anyway they confirmed no action from my side
)
My assumption was that I got biometrics payment request for new application # on the 12th. (+-1 day for ecas vs mails that is normal)
No related info in GCKey.
#5 I think this is BR, which I got via GCkey.
I'm confused why they used "a letter". But I used this word for "mail" for a long time too until someone native English speaker explained me the difference
(In Russian we use the same word for both)
So my question was does BR in ecas looks like "5. We sent PA a letter on February 25, 2019. Please consider delays in mail delivery before contacting us." , thank you
