good luck to your fiancee's interview. tell her to relax, be focus and confident in answering during the interview, just answer what is asked no more no less and be consistent as they repeat some questions in different ways so not to wonder or get confuse. when she arrives there she should be confident in looks, not nervous as she is under observation when she enters the embassy especially while waiting for her turn and after the interview. just have some practice answering possible questions then she will be familiar on things. good luck to both of you i know you can both make it.
