回复：急！！恳切请教8老师及其他好心人

一直以为TN签证12月底过期，糊涂人才发现I94已过期170天。现又找了一工作，需办TN。现在就过境去办有麻烦吗？怎么办才好？多谢了！
-You have no choice and have to leave US now immediately before your unlawful presence is > 180 days (from the date your I-94 expired) even if it is possible you might still have a problem to get the new TN I-94 at the border due to your current unlawful presence. Otherwise, you will be subjected to 3-year bar if you leave US 10 days later from now on.
