I urge everyone to stop focusing on IP1/IP2...etc, as they hold no bearing whatsoever in determining the stage of an application.
They are made up terms, and sometimes bring more confusion than clarity.
Many applicants see their BG status stuck in the same so-called IP1 wording for months and months without any update, thinking their file is being forgotten or fell in a problem, only to get PPR a few days later, without ever seeing so-called IP2 status.
The same holds for so-called IP2, where people think they are close to PPR, only to realise it's taking longer than initially expected based on IP1/IP2 assumptions.
Some applicants I know have seen their BG status in "Not Applicable" throughout the whole 6 months process! Needless to describe their stress levels during that time, while everyone was talking about IP1/IP2 everywhere...
As far as I'm concerned, my status has been showing so-called IP2 status, "We are processing your background check" since day 1, as soon as I got AOR on Sept 21 2018. Never changed to anything at all, till this day.
Just chillax, let them do their work, and order GCMS from time to time to make sure everything is going well with your application. It's the only reliable way to know where you're standing, and at what stage you're at...
All the best to all.
