第一次回来签H1B，之前是F1， 刚开始员工检查的时候发现大使馆的系统里显示的我的H1B截止日期是2022年，但实际上应该是12/31/2021。在27号窗口白人小哥那签的，我和他说之前检查发现对方系统和我的实际h1b截止日期有出入，但我所有的h1b申请材料上都显示应该是12/31/2021. 他一阵检查然后说应该是系统搞错了。他全程问了两个问题：
VO: what do you do at XXX?
me: I am a... (my job position)
VO: how long have you been working at XXX?
me: almost one year. I joined XXX on July 1, 2018. I used the OPT for the first half year and then changed to the H1B status.
VO: it may take 1-2 days to correct the error in the system. but you should be able to get your passport in one week.
