All AOR are sent from Centralized Case Processing Center, Sydney for everyone. We would know our local processing office when we get the test invite.Thanks. Its the same for me. From what i have heard , LPP will most likely be done by Sydney and your local office will do the rest like background, test oath etc. Sydney was very slow in past, but they are not as bad as before. I have heard people getting everything done in 4 months. So lets see. One of my acquaintances and his spouse had same primary and secondary office. But he got it in 4 months and his spouse was waiting after 6 months.
