Yes, I found that form for emailing. That's where one must select a US city to which the application was sent, even if it wasn't processed there. Given my experience thus far with UKVI, I am anticipating that selecting the wrong city will result in no information and having to pay again to email again. I'm wondering if anyone has emailed through this form and how you dealt with their requirement that you select a city that may not have anything to do at all with the application being enquired about.
