I'm an EU citizen who's on the organizer team of Elm Camp 2025, and I'm really on the fence whether to even risk the flight to US and attending, hearing these stories :(
First, do it for your own safety. A wrong form or the wrong answer to a verbal question after 18 hours of travel could land you in weeks of brutal detention.
Second, do it to help the cause. We here in America need to suffer the consequences of our actions. We need to see conferences canceled. We need to see imports stopped. We need to see people refusing to bring their knowledge and expertise here.
It is going to be a long, dark four years for the globe. It's going to take all of us working from within and without to have any hope of dismantling this evil empire.
What visa do you hold? I wouldn't be confident that organising a conference would fall under ESTA or B1, speaking at one should be, but ultimately it's upto the goon looking at your application at the desk. In any case ensure you immigrate as early in the day as possible to maximise the chance of a quick deportation if you are rejected.
