It was a great experience during my USEM interview. I arrived there at 6am. The Filipino interviewer in the Prescreening was nice and I think it only took 3 mins interview with her. Moving forward, the American Consular officer was very nice too. After asking me some questions about me and my fiance, she asked to see our pictures together and didn't ask for our ongoing communication(chat/emails,etc) anymore. I think it only took 5 mins with her. It was really a smooth process for me. Thank God!
