在美国留学生签证（F1）面签时，并没有官方要求的语言，但是最好是使用英语面试。但是如果实在是交流困难，也可以使用中文，面签官一般都在中国生活过5年以上。在面签是，签证官是会根据申请人的水平，简单问一些和申请人水平基本相当的问题的（当然，有的时候也会懒得问），一般不会出现特别刁难的情况的。
需要注意的是，你的英语水平需要和你申请的学校及你提供的语言成绩（托福）和专业考试成绩（SSAT,SAT,GRE,GMAT等）相符合。
比如说，你持有的有条件录取的OFFER，也就是先读语言或预科再进专业的那种，这种在面签时英语水平差一些问题是不大的。夹杂着中文也无所谓。
但是如果你拿着TOP30大学的OFFER和110分的托福成绩单，却无法正常沟通的话，签证官是会怀疑你成绩造假的。
我不认为如果你到美国读书却不能够进行最基本的交谈而签证官会给你签证
this will be a joke if he do so
好好的准备你的签证.In English
good luck
Use English of course, if you think you can converse in English.
Otherwise, the American Immigration officer will want to know how fluent your English is. If you do not have fluent English, how can you handle the university course study exclusively in English?
In fact, the American Immigration office does want you to show acceptable TOEFL score. That means you should have the ability to converse in English.
However, if your English is really embarrassingly poor, then, you are better off talking in Chinese.
