ms. vaughan? >> thank you for addressing this problem. it was cold one of biggest frauds ever perpetrated on the trade government and i know they're still cleaning up a lot of the fraud like programs that were passed in the '90s. we know a fair amount about the benefit of fraud that occurs from programs that were built into uscis on the quality control programs, assessments. there's double-digit fraud in some of our legal immigration programs now, and we have to have a system that has integrity to have the confidence to go forward. i agree with a lot of what my colleagues said, which would add there needs to be and interview process at a certain point in the system. we can talk about way that best fits in but we can't have a system that is an honor system or people are just taken at their word. and putting the burden of proof on the applicants is important. using technology to verify claims that people make. i agree wholeheartedly that there cannot be a strict confidentiality provision in this. that's a dealbreaker. we can't prosecute all
