Oh okay, thank you. However, I didn’t get our Pre-Arrival through email, I got an email saying I have a message in my IRCC account. I got Pre-Arrival (PDF doc.) in my IRCC account. Also, just checked and no location stated on letter.You can just look in the signature of the email but easier and reliable way is to do ctrl+f.
Zero chance of you missing it written in that email, if it is.
Both mine and my brother's application was transferred to LVO in AOR2, but in Pre-Arrival email it says Warsaw and in my brother's PPR it also says Warsaw. Based on how quick your application moved, similar to ours, I would think that yours is also being processed in Warsaw.
