I'll be flying out of YYZ to the US in a few weeks...and this is the first time I am applying for a TN visa. I've gone through some blogs about the TN visa, but also curious about other FT'ers experience. For what it's worth, I've a family and home in Canada, and have no intention to immigrate to the US (so no dual intent from me).

Few questions:
For those of you who've been through the TN interview process...was it straightforward?
I'll be driving into Pearson from over 3 hours away, so just trying to see which flight I should book to ensure I have enough time set aside for the interview itself. How long should I factor in for the TN visa interview?
