Why do you need the timeline?!? I filled a K1 visa application. Got approved. Got the case number from the NVC. The case went from in transit to ready the Frankfurt Germany Embassy. I then filled out the DS 160 form immediately. I took the application number and created an account on the Apply for a US visa in Germany website. I paid the $265 visa fee and was told we would get an email stating when we can schedule the interview.
wanting exact dates is not relevant here.
I don’t know what a packet 3 is. Can you explain? I’ve done so many internet searches and haven’t came across packet 3.
