The Cardinal Care waiver deadline is 9/15/2019. It costs $5500 for the academic year. As an international student, I've gotten many questions from incoming freshmen and other international students about their options on the mandatory insurance. I have been using the ISO insurance, which satisfies all of Vaden's requirements and costs only about $1000. There are two options available and both satisfies Stanford's requirements. Within a few hours after you purchase the plan, an agent would email you the Vaden waiver form, and all you have to do is to submit it on Helpsu to save more than $4000 from Cardinal Care. https://www.isoa.org/?ref=2760344
