It is CIIS policy that F-1 and J-1 visa holders have health insurance while studying at CIIS. Students can provide proof of coverage in English from their home country or from a US insurance company. This document provides information on understanding the admittedly confusing world of health insurance in the US. More details are covered at the New International Student Orientations.
CIIS does not endorse any one company, but can provide links to various insurance companies that folks have used in the past. In general, the more expensive the plan, the more coverage one receives per injury/illness.
International students on the F1 visa are not eligible for Medicare or Medicade health plans. Enrollment and usage of these plans can have negative impacts on your F1 visa status and/or future visa applications.
