-Can the DS-156, DS-156K, DS-157 and DS-230P1 forms be printed and submitted on A4 paper, obviously the US use LETTER paper and all the documentation they have sent me is printed on LETTER paper.
-Do people tend to use recorded delivery to return the completed forms, or has standard 1st delivery proved OK?
-Do I need to attach the passport size photos to the two copies of DS-156, or will that happen during the visa interview using the two passport photos I have been asked to provide (sorry sounds obvious, but it doesn't seem to be spelled out).
Thanks to anyone who can add anything o these questions
