Yale international scholars generally hold J-1 or H-1B status, with the vast majority using the J-1 research scholar/professor status. For a smaller number of scholars, there will be several other options, such as E-3, F-1 OPT, O-1 or TN. Listed below (by Yale position) are the visa categories most often used by Yale international scholars. The first visa category listed under the position is the one that is primarily used, with additional options listed below.
This is a general guide with suggestions about the best visa status for particular titles. The final decision about which visa status to use often comes after a discussion between the hiring unit, OISS and the scholar. If you have questions about the most appropriate status, contact your OISS adviser. If you are not familiar with sponsoring international scholars, please review Appointment Dates and Funding.
Note: All sponsorship-required positions must be full-time (100% FTE) on-campus or at Yale-affiliated business premises in Connecticut. Remote work outside CT is only permitted depending on the specific visa type and for substantial business purposes where the assignments cannot be completed on campus. If the specific visa category allows entirely remote work, approval by an appropriate university authority would still be required.
