I am currently working in the US and my TN status expires next August. I am going to Europe for work in July and I am wondering if I can renew my TN at the airport (likely Houston, Dallas or Chicago) on the way back so that I don't have to do a special trip to Canada for the renewal.
The HR person at work seems to think that I have to enter the US via Canada so I am trying to make sure that my interpretation of "any point of entry" is correct.
thanks.
