A couple of my regular go-tos have been to the U.S. this summer and I mentioned to them some additional tips to avoid potentially being detained.
Yep, I just got back from the USA recently. After getting facial and finger scanned as U.S. Immigration, I was questioned for about 20 minutes about an incident 11 years ago when I was denied at the border on the way to Miami. Mind you, since that traumatic experience I've been to the U.S. multiple times each year since then (not including the pandemic) and never got questioned or stopped before. Anyways, I just answered everything in detail and eventually I was allowed to continue on my trip.
