Thanks! Got my FP request on September 2nd. Gave FP on 6th September. Now we wait for the test invite to follow. Currently it says "not started" against citizenship test.I wouldn't worry about it. As far as I understand, Sydney does the BG checks and sends the file to Local office for test scheduling.Some local offices are ahead of Sydney and they send the test invite before BG is done .From what I see , in case they need FP to verify ,they ask the Local office to deal with it and the email comes from the local office...which may be the case for you. Assuming they started the BG and need Fp and delegated it to your local office.
Again this is just my theory, I may be wrong. The good news is that they actually started "processing" your file. I see people from even August whose files havent been touched at all. Keep positive, we will all get there
