In addition to asking for details of every school you went to, every job you had, every country you've been to, they ask you questions like this:
>> Have you ever violated, or engaged in a conspiracy to violate, any law relating to controlled substances?
>> Are you coming to the United States to engage in prostitution or unlawful commercialized vice or have you been engaged in prostitution or procuring prostitutes within the past 10 years?
>> Have you ever been involved in, or do you seek to engage in, money laundering?
>> Have you ever committed or conspired to commit a human trafficking offense in the United States or outside the United States?
>> Are you the spouse, son, or daughter of an individual who has committed or conspired to commit a human trafficking offense in the United States or outside the United States and have you within the last five years, knowingly benefited from the trafficking activities?
>> Have you knowingly aided, abetted, assisted or colluded with an individual who has committed or conspired to commit a severe human trafficking offense in the United States or outside the United States?
>> 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 or do you intend to provide financial assistance or other support to terrorists or terrorist organizations?
>> Are you a member or representative of a terrorist organization?
>> Have you ever ordered, incited, committed, assisted, or otherwise participated in genocide?
>> Have you ever committed, ordered, incited, assisted, or otherwise participated in torture?
>> Have you committed, ordered, incited, assisted, or otherwise participated in extrajudicial killings, political killings, or other acts of violence?
>> Have you ever engaged in the recruitment or the use of the child soldiers?
>> Have you, while serving as a government official, been responsible for or directly carried out, at any time, particularly severe violations of religious freedom?
>> Have you ever been directly involved in the establishment or enforcement of the population controls forcing a woman to undergo an abortion against her free choice or a man or a woman to undergo sterilization against his or her free will?
>> Have you ever been directly involved in the coercive transplantation of human organs or bodily tissue?
And now, this.
And don't get me started on the stupid fact that you cannot renew your US visa within the US, and in the end people on student/work visas have to take the pointless trip to Canada/Mexico just to get a new visa.
I hope someone eventually realizes visa applicants are people too.
