Can a TN classification denial result in immigration detention? If so, how can I mitigate that risk?
For context, a Canadian woman recently tried to enter into the USA from Mexico and get TN-1 status. Instead of refusing her entry, officials detained her and she's been stuck for 10 days waiting for deportation.

It's unclear to me how big of a risk this actually is for the average "Canadian goes to the USA" story because of her specific factual scenario. Presumably I don't want to enter from Mexico, but is it advisable to take flights from a TSA preclearance airport in Canada so I'm not actually in the USA if the classification is denied?
