回复：Urgent! 8 老师 或有经验的老师请帮忙， h1b期间加拿大回美入境证明！

我去年h1b 期间开车去了加拿大几天，可是回来入境的时候没有换i94，海关就让我进来了，护照和i94上没任何记录和盖章。现485要求补充材料证明最近入境的时间，请问我怎么证明呢？谢谢！
 

另外，我的加拿大签证是从2013 到2018，上次入加拿大时加拿大海关盖章盖了2011年，我后来才发现，同行的几个家人都盖错了。但主要是入境时没章，怎么办？非常感谢！
-It seems you used this entry as your last entry to US in I-485. Thus, USCIS always ask you to provide the evidence such as I-94 and you don't have it because you used the automatic visa validation rule. You may go to the local CBP Deferred office to see whether you can get the I-94. If no, you may just explain it in the response letter that you didn't have a new I-94 for that entry because you used  automatic visa validation rule.
