准备提交perm，顺便查了下自己的i94，发觉网站上（https://i94.cbp.dhs.gov/）自己的travel history中departure的录入信息有误，
当年进入美国还是纸质i94，今年1月中离开美国回国就在机场把纸质i94交给航空公司了，2月中回到美国，现在发觉那个网站上我的departure time竟然在我2月中进入美国后的10天？难道我现在已经被认为不在美国了？
问1：各位的travel history都正确么？我这种情况要去联系改正么？
查了一下CBP官网上faq，
有这么一条：
What do I need to do if my departure information is incorrect or inaccurate?
Answer: The information provided on the website is information found in CBP systems. If you are departing by air or sea, your departure is recorded electronically. There may be times when this information does not appear accurate. Upon departure, this information is verified and then confirmed in CBP systems.
问2：各位怎么理解上面这段话的？就是说departure有错很正常？？
谢谢。
