So-called IP2 status "We are processing your background check" doesn't hold value in determining at which stage your application is.How much is the general processing time from IP2 to PPR or COPR
How much time it will take for PPR depends on dozens of variables specific to each and every case, and nobody can tell you when you'll receive it.
The only reliable information is that it takes 6 months to process your application, assuming everything is fine with your application. If some elements need further review and scrutiny, it may take longer. Especially if there are security concerns.
