You are better off scanning them and kiosk instead of leaving in drop box
There is a drop off box located on the inside just on the side of the door. Scanning is not currently an option due to covid.
I would not leave it in the drop box. Paper work seems to not make it to the correct location. There is a machine in the lobby where you can scan the documents directly to your case. Or you can turn them into the window where you get a receipt as proof it was submitted.
Send them in the mail I'm not sure about drop box
