Maybe on endorsement level there can be some special treatment but on federal level i don’t think any such treatment is given to applications. And yes employee retention rate of employers who are taking part in this program since 2017 plays a good role in swift processing,as it opts out the fraud-fake employers/employee thing.
Thanks for your explicit answers. What stage are you currently in on the AIPP stream. I saw a post sometime last where you said you've successfully received your endorsement from NS within three (3) days. Am I right? Have you applied for your PR or probably still gathering your documents as this process requires carefulness in order to put in the right documents.
