My OWP was returned and sent back in aug 22nd so maybe that is why it is delayedNo news from OWP yet? Some July applicants already got OWP approval, but some others not, but dont panic, the regular time is 4 months.
In general your medical should come after OWP approval, but for some reason many of us is getting meds before OWP.
I know PR and OWP are processing separately so, one thing doesn't depend on the other.
According to your timeline you should hear from them this month.
