ask your friend did how many ghost updates did she received? Maybe my ghost update is either regarding something completed or something started. Dont know!!
tracker got updated. My eligibility and background both the same meanwhile other people with same AOR and few with AOR after me got their eligibility completed. IRCC is unpredictable as *******
One of the immigration lawyers mentioned on youtube that IRCC has now developed a standalone chinook system. I'm not 100% percent sure on how true this is but the best we can do is speculate.
If we look at the trends, they are following AOR dates.
