I have submitted my application for ILR tier 2 route back in June 1st. I did this via a solicitor. I received the invitation to upload documents and picture through the app on September 6th (opted in). I am still waiting for the decision.
While reading the forum, I noted many have used dual submission which seems to have made things much quicker. When I contacted my solicitor, she said it is not possible to do this. Can someone here kindly help me explain how this works and point me toward some documentation about this so I can share it with my solicitor? She is adamant there isn't such thing as dual submission

Thank you so much
