Hello dv2010winner my case number is 2010SA00000xxx I received the 2nd letter two weeks ago, there I have the date and time of the interview but says I should contact the Consulate to confirm the interview, I e-mail the Consulate but still no reply and the date for the interview is march 4th. I saw you have a similar case number and the interview on the 8th so maybe you can tell me how did you confirm yours.
thank you very much
