Slip one part of your latest post I can help with is don't worry about the documents you need to leave behind for the application because there is always something else needed in my opinion.
Yes the Xmas card same as me

but even if you need to send something else which is needed then use DHL secured mail, it gets there within 5 days, thats what I did with my wifes application.
