B2, 入境章上停留日期是Mar 28 2015. 本计划June 24离境回国。
网上I-94日期是 Admit Until Date: 2015 June 28.
我们决定以网上时间为准。
现有另一担心：
出关时会检查visa，这样会看到是逾期停留，对吗？
-No. They only record when you leave US. If you leave US after the I-94 expires, it may affect your future visa application or even affect your next entry to US (depends on how long you overstay).
询问了最近回国的同事，说不需要上交电子版I-94，那么如何记录离境时间呢？
-They scan your passport entry stamp page to determine your identification, and automatically record the date you leave US into the CBP/USCIS system.
谢谢！
