Regarding this issue, i would like to share with you something happened with me, few months ago , i sent email to the US embassy in Cairo asking for what documents to translate?, and they answered me with, dv winners are not required to translate thier document...., i was looking to the email wondering ! OMG how !!! saying to my self " all document in Arabic" so how the employee saying that to me?!! , he does not know the instruction!!!" saying to my self ", and finally i decided to ignore his advise and i will translate all the document, but now i see you also saying that translation is not required, so the employee was RIGHT, hmm i have read in the instruction that all document not in English should translate into English,, what do you think about this??
i have another Q ,i'm DV 2014 winner but i won with old photo, i mean i submit on 2012 old photo not present one as they asked
and of-course my face features little changed " for example i'm fatter now

so, have you ever read or aught any one refused cause his submitting photo in October was old one?
by the way, i sent new photo to K CC with my forms.
hope to get answers
