As you are FSW- O, After medicals pass then
1.Review of additional documents may change from NA to "We do not need additional documents" or " Additional doc required"
2.Background check changes from "NA" to "Your application is in progress. The next step is to conduct a background check." and then back to "NA" after days/weeks and then after a month or so it may change to "Background check in progress..." again.
3. PPR normally after background check in progress.
This may not happen for all applicants as some have not had any background check changes and have received PPR in email, so you would need to check your profile daily for any changes/updates.
