Good questions! We received a white form with my wife's name and case number filled-in by hand near the top and a checklist of requests for further work on the application; for us, the "updated police report" item was checked. I think this form is called a 221(g), but it didn't have this code on it so I may be wrong. We didn't pay any fees at CITIC for sending forms, and I turned in the documents without an envelope so that the bank employees could inspect them before they were sent. Hope that helps. Another quick question about the requested documentation submission form. Any idea what the UID number is or where I may find that info? Is it on the barcode attached to the passport? yes, it's the barcode attached to the back of the passport, it's also in the appointment confirmation email.
