A Visiting Student Researcher (VSR) is not eligible to receive academic credit, cannot be paid a stipend, and does not have an official "academic" standing at Caltech. VSR's are also strongly urged to provide proof of insurance for the duration of the visit, since they are not eligible for Caltech benefits. VSR's may be reimbursed for research-related expenses, but will not be eligible to receive a stipend through payroll. Examples of research-related expenses include travel and equipment, but not lodging, meals, per-diem or other expenses related to the cost of living in Pasadena. This status is limited to short-term visits of no less than one month to no more than one year, with no extensions.
