Hi,
I am Jan 2017 applicant, AINP, AOR - March 2017 and my background status is still showing "We are processing your BG". Not sure if that's good or not.
I also received a reminder letter in back in June 2017 asking for Passport, Police Certificate, Sch A, RPRF. At the end of the letter it stated "If you have already completed all of the requirements mentioned above you can ignore this letter". Since I have sent everything, including RPRF since the beginning of the application, I didn't send more information after receiving the letter.
We'll see how it goes.
