Processing desk — AD Category-I bank and the supervisory window
What actually happens to the file after you press submit.
Every submitted application lands at an AD Category-I bank first. The bank works the file desk by desk and pushes it into the six-regulator window. On the Automatic route the window clears by machine and merely records the result; on the Approval route it stops until named officers sign.
In plain words
This is the back office made visible: your bank checking the paperwork, then the regulators either ticking it off automatically or personally signing it.
No filing is visible from this desk yet. Nothing has been filed on the rail.
