回复：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！

Yes. I know this rule. I was asked to provide the proof for the most recent time to enter USA. Does it count for this case (back USA from Canada)? If yes, how can I provide proof. Thanks!

"访问加拿大30天之内，不换I-94，不盖章". = 你的3天加拿大之旅不算出境。It does not count for the most recent entry.

"provide the proof for the most recent time to enter USA. " = 你的3天加拿大之旅之前的一次出境。
