The DS 160 form for visa to the US asks those famous questions:
Do you seek to engage in espionage, sabotage, export control violations, or any other illegal activity while in the United States?
Do you seek to engage in terrorist activities while in the United States or have you ever engaged in terrorist activities?
Have you ever ordered, incited, committed, assisted, or otherwise participated in genocide?
Have you ever been directly involved in the coercive transplantation of human organs or bodily tissue?
obviously, I don't intend to answer "yes" to any of these questions. Why they ask them at all is a question, but maybe a different one.
My question is: What does actually happen if someone were hypothetically to state here that they've participated in genocide or stolen body parts? I'm asking if there is any kind of official procedure, government guideline, or even law that governs that.
Aside from the obvious cases, there's a few that might actually come up, such as the question about prostitution in the past 10 years (for people from countries where prostitution is legal). Or the question about being member of a paramilitary or resistance group where such groups are officially US supported, etc.
