AP question!!!

[MiSeRaBle123 0]

Hi, i had my interview for k1 visa at London embassy last October and i have been under AP since then, yesterday i called DOS and the lady told me that i should send my passport to the embassy, and she said that the consular section sent me an email requesting my passport 2 weeks ago ( although i checked my email and i haven't received nothing from them) i asked her if AP's cleared she said no, it's still pending but they need my passport!! what is that ??? and i asked her if my case is at the embassy or washington DC and she said embassy.

Anyway i've sent my passport thourgh royal mail and now i found out that i should've sent it through DX :(

what shall i do ? how i'm gonna receive my passport when the visa is issued?? do i have to call DX or the embassy??

if they are gonna issue me the visa then is it gonna be in a few weeks or it might take months again?

usually when London ask for passport do they issue visa right away or what ???

have anyone been through the same situation in the uk? please helppp i'm so anxious
