北京 B2 1000 check

背景介绍：我是中科院在读博士，女朋友今年去美国读博，想在寒假的时候过去看她

面谈过程：约的是星期五下午两点，一点到达大使馆排队，人不算多，实际上两点半就出来了。签证官一上来就直接说中文，（可怜我还用英文介绍了好一会）问了下女朋友什么时候过去的，读什么专业，读几年，然后又问我的专业，其他的什么都没问，（我还准备了十几个问题...)大多数时间都在电脑上核查，然后就撕办护照邮寄的绿条了，还说你不要担心，已经过了，一个月后打电话通知你来拿
收上去的材料有护照、DS160表和我女朋友写给签证官的信，以及我的CV、在读证明、实验室和导师介绍，估计是要审核我的专业吧。其他的材料如我女朋友的、证明我们关系的以及我证明我家里情况的材料，都没有看
