I know of someone who submitted an ISU Clearance last week. If they get it without fulfilling the residency requirement (they just teamed up a couple of months ago), then what I was told is correct -- that as long as one of the team has citizenship, it is okay (if the team does not have citizenship, then they need to have residency)
I was also told the rules are not as different as they were before, and one casualty of that was a Dutch team that was neither Dutch nor did they meet the residency rules because they trained in Italy, so they lost their ISU Clearance.
Will post again when that skater gets the clearance to transfer to a new fed, even though the skater does not meet residency requirements yet
