Sure, I can elaborate.
We used Webwed to officiate, a zoom wedding basically. My wife and I were in the same physical location in Ireland with our folks on the call with the officiant in Utah.
Everything went great! We got our marriage certificate, with the seal and stuff.
At the time the proclamation to travel to the US was in place because of the pandemic meaning only citizens and/or their spouse could enter.
I was entering using my ESTA/VWP with no intent to immigrate just to visit family.
When going through pre-clearance in Dublin I was called into the back room to wait while they scrutinized us.
After a while he called me to the counter to ask about the wedding.
He said something along the lines of not everyone was physically present at the wedding and we proclaimed that we were.
He retorted by saying the officiant wasn't so not everyone.
He denied me entry saying I'm legally married in Utah but it doesn't work for immigration/CBP and quoted an immigration act partially:
(35) The term "spouse", "wife", or "husband" do not include a spouse, wife, or husband by reason of any marriage ceremony where the contracting parties thereto are not physically present in the presence of each other
Anyone familiar with it might notice the bit that's missing from that. Here it is in full:
(35) The term "spouse", "wife", or "husband" do not include a spouse, wife, or husband by reason of any marriage ceremony where the contracting parties thereto are not physically present in the presence of each other, unless the marriage shall have been consummated.
He never mentioned it nor asked about consummation, how we'd prove it would be another story but he picked and chose what parts to use.
CBP are human and make mistakes like the rest of us, that day we got a dude who made a mistake and revoked my ESTA and my ability to use the VWP.
To fix it we had to make an appointment to apply for a B1/B2 visa to even visit family. It took us 2 years to iron out.
