I am a Canadian on TN-1 status, living in Metro Detroit.
I got my TN in June 2017 with an expiry date of June 2020. When I first received my TN, I got a correct I-94. When I briefly flew out of the US for a trip in November, I got a correct I-94 upon re-entry.
I drove to Windsor, Ontario this morning and returned the same day. I used the Nexus lane for both trips (my Nexus card is linked to my TN). I showed my November I-94 to the US CBP guard on my way back.
When I went to check my new I94 on the website, to my shock it said my class of admission is F-1 with an "admit until" date of "D/S". Even stranger is that the "record number" is identical to the record number issued on my I-94 from July 2016, when I was indeed on F-1 (I was a student from July 2016 to May 2017). It looks like the computer system glitched big time, since if the CBP guard had entered my admission class incorrectly, I should have still received a new "record number".
Is this something to worry about? Should I waste an hour driving to Detroit Airport to get this resolved?
