回复：回复：请问有人知道TN Visa 有没有probation日期吗？

I am new at all these. I got denied at the border once, job description not matched. Tried agian at the airport before getting on plane, denied again. Then wanted to leave without applying the TN visa, but was not allowed to get on the plane. Should I apply for the waiver or what else I can do for this? Such a mess.
