Thank you, Chair.
In that case, my question is addressed to both Mr. Kurland and Ms. Kane.
I'm impressed with your knowledge of how other countries manage this risk. A temporary visa, really, is a question of managing risk. I would like you to comment on how we manage this risk properly so that we screen out that 0.01% potential of a person causing our nation a problem because, as you mentioned, the majority of them are bona fide visitors or students who may just want to come across the border and go back to the United States. What is the best strategy we can have to manage that risk?
