Has anyone actually been refused crossing the border in either direction at Lukeville? Or really even questioned about essential travel? Not to the best of my knowledge.
I came back in July 2020 and was told that it was essential travel only. I told them that Mexico considers tourism essential. The agent just looked at me, said okay and waved me through.
I went north through Lukeville the day Trump visited the border wall in Yuma and had a CBP agent give me enormous crap about traveling before he inevitably let me in. He was really ugly. A couple minor ones around the same time. Recently very nice. We have a house guest in Arizona who crossed up through Nogales yesterday morning who said she had a long pleasant conversation at the checkpoint.
