I never said the siblings were duplicates. I said it is unclear how IRCC is policing the list to differentiate multiple applications versus fraud in general. It was outsiders that brought up to IRCC the fact that there were duplicate applications a few years ago. Some applicants had been accepted and may had already been approved when it was discovered they had submitted multiple EOIs. It is unclear how the list is being policed.that is not duplicate imo, both siblings are eligible to sponsor so they both should be given a ticket to lottery.
