Sponsorship breakdown is uncommon in the SAH community. The reason is that either they're family linked, or the organizations are already well placed to do the sponsorship. It would be a rare thing to see a sponsorship breakdown. It would happen only because of certain specific conditions, for example, if there is a secondary migration, or if there is an issue where the demand is a lot more than what is being provided. In that situation it could occur, but I'm not aware of any breakdowns.
