约的下午两点，到大使馆的时候一点半，前面已经排了很多人了。
个人感觉在厅外排队还是挺快的，之后便是存手机，u盘，后面便是排队交材料。交完材料后又在签证大厅外排队等待采集指纹，话说轮到我时指纹采集颇费周折，我听不懂那个工作人员的中文，后来她还不太高兴，不过最后还是成功了。剩下的便是排队等待面签了。刚开始时只开了六个窗口，队伍行进很慢。马上四点了，又开了三个窗口，等到我的时候已经过了四点半，累的有点不撑了，还好5号的白人大叔看上去还挺和善, 我就走了上去
ME: nice to meet you, sir
vo: nice to meet you too.
我递上材料
ME:here are my documents.
vo翻了遍材料
vo: oh, phd, good. how old are you?
me: **.
vo: what's your major?
me: physics.
vo把i-20，sevis收据和offer letter退了回来，留下了ds160确认页和护照。
vo: have you been to us?
me:no, i have never been abroad.
vo:do you have an advisor?
me: currently i have no advisor, there is a prefessor i am intertested in, do you want to look at it？
vo：no，okay。
之后有两分钟，vo一直在盯着电脑敲个不停，我估计要被check了。
vo：do you have a study plan?
me: yes, here it is.
vo:your visa is approved, but we need 3-4 weeks.
me: ok, thank you, have a nice day.
vo: thank you, you too.
vo留下了resume，study plan，自己走出大厅取回手机，赶到邮局去办理自取。
