>> Are you a member or representative of a terrorist organization?
Assuming you are: you answer yes and you get denied a visa (duh). Answer no and the gov doesn't know, what happens? You commit terrorist activities on American soil and get charged with that activity, which I assume is FAR worse than the punishment for lying on a Visa (if it isn't, somethings wrong). Can we not kick out a terrorist (found out after they entered) without this question?
It seems like the same goes for every single one of the above questions (except the first one, "Have you ever done drugs"). Every one of these questions is always going to be answered with a no, so doesn't that just create noise in the data?
