J-1 今天北京签证被check了，有点感触

kylesonUID: 2762040

这东西完全是运气，不过还是有点技巧~

首先我填的是DS-160表，新表和旧表的面签是分开的。而用新表的人还比较少，所以DS-160的队伍人比较少，但是签证官也比较少，就两个，一个人亚裔一个是美国MM。亚裔几乎就是水过，MGMM比较较真，队伍进行的太慢了。结果眼睁睁的把我分到了MGMM那里。我前面是两个参加国际展览会的商务，居然有一个被拒签了，想不通。
全程中文交流，我还努力的用英语回答，毕竟J-1有英文要求的，而且我又是年轻人，尽量还是讲英文吧。

虽然大部分靠运气，但是还是有点小小技巧

1.面签顺序完全是交材料的顺序，并不是预约的顺序，而且时间也不一定。我预约的是下午两点半，但是我一点半左右就进去了，所以尽量早去。去了先不要急于交材料，先观察一下，看看有几个签证官，前面排队的有几组，然后根据组数排列一下，看自己会被分配到哪组，然后再交。

2.J-1签证的一般时间为1年左右，所以不要赶在和一堆短期出国的人一起签证，和比自己出国时间长的人一起通过的可能性会更高。这个本人估计要看季节了，就像现在这时间段，出国探亲，旅游，开会的人比较多，出国留学的并不多，所以本来很容易过的J-1签证居然被衬托的很有移民倾向了。我今天就是和一些探亲开会的人一起，一组里面就我一个留学的，不check我check谁呀，不拒签我就已经给我面子了。

虽然说大部分靠运气，但是还是把材料好好准备吧，尤其是研究计划和简历，毕竟check了就靠着东西来争取机会呢。
