Maybe they simply send the notifications to the last file they process, which is most likely not the PA I guess...
Hi Twiny41,
Sm1smom is right (as always ), they should send NOA to the principal applicant. I have noticed that you married after the selection. We also got married after I found out that I am selectee. Maybe this is some sort of test for newlyweds . I hope, they did not consider our applications as marriage based. At the biometrics appointment, the officer asked who is our sponsor for GC and we explained that this is DV Lottery case. At this stage of the process,we are waiting for interview letter. Good luck!
