I went to apply my
TN last saturday on 7/25/09. I was afraid that the tunnel(yes, I went to the tunnel) won't be able to process my TN because people in this forum are saying that. However, I called the tunnel twice before my trip there, the answer I got is "We prefer process the TN during the weekdays, but we do open on weekends."
So, I went there, got my TN w/o any hassle, but somehow they took my fingerprints which I haven't never done that during the several TN I got over the years.
There is no best POE whatsoever, the most important thing is your got your original degree(s) and the offer letter with sufficient information for the job.
Good luck to our fellow Canadians!!
