Our case is still At NVC too, and I'm hoping for some progress next week! I reached out about the KFTP letter last week through PI but haven't heard back yet. I think once the case moves to In Transit, we can contact the hospital to schedule the medical exam and check with the Embassy to see if they've received our case so we can go ahead and schedule the interviews. From what I've read in forums, it seems we don't need to wait for the welcome letter by mail; we can book interview slots with the digital KFTP letter. Kindly Keep us posted if you hear anything new or any update.
