I just spoke to IRCC agent on call. He told me that office is aware of this situation and they will resolve it. He told me that it looks like some administrative error or glitch from IRCC side that I did not receive oath invite for my son with mine, I should receive his oath invite. This is my 3rd call to them and all 3 times, I got different responseParentage - meaning parent background for child. Maybe if I’m related to the child or father
