I believe the term "citizenship hearing" is different from "interview." Based on my understanding and confirmation from the group, an interview is a step that may occur before the completion of a background check. On the other hand, a hearing takes place prior to the finalization of (LPP) process.
It's important to note that not everyone will necessarily go through both an interview and a hearing. The decision to conduct these steps is at the discretion of the officers involved in your case, who may require further clarification or information.
I have an interview scheduled. But Background is marked as complete in tracker.
