My interview was on June. 23 at the US Consulate in Jerusalem. The interview went very smoothly, and they asked me a total of 4 questions and did not look at one piece of the backpack full of evidence that I had taken with me in case needed. After the interview, CO told me that everything was fine and that they just needed a form I-864a from the co-sponsor's spouse or W2 form. And that as soon they received the form, that visa would not take more than one week to be ready. After that, they instructed me to leave my passport at the consulate.
