I hear you man. The eligibility review is a time consuming process. Check my post here:What’s your TFN no.? Is it starting with 0027 series or 0026?. Depends on ircc officer! I received this stupid TFN more than an month ago but NO USE AND CAN’T LINK TILL DATE!!!
Don’t why they take such long time periods!

At first, they will check if all of the submitted document are correct and valid and then it will be assigned to an officer for decision.
Once they finished, you will get your AOR.
