As long as the sponsor doesn't have some extraneous reason why they cannot sponsor, the sponsorship will be approved.
As long as the PA is a member of the family class, with a sponsor, they will get AIP. If they question something, they will contact to ask for more proof, and before they just reject an application, they send a Procedural Fairness letter. That gives people a last chance to correct something.

Try not to focus too much on it. That's the biggest mistake I think people make. When you focus on something totally outside of your control, you end up stressing out for no real reason. You will be given lots of time or opportunity to respond to concerns, if any. So, try not to worry.
That's the ultimate message here: try not to worry. Let them do their job.
