In the sections below are descriptions of the various appointments and the terms associated with them.

The academic appointment of Research Affiliate recognizes the status of an individual with whom the Institute wishes to acknowledge some degree of association.
Appointments to this rank are not normally intended to be long-term or of indefinite duration.
Appointments to this rank are without salary. Research affiliates are not employees of the Institute and do not participate in staff benefits programs.
Appointees to this rank must report their outside professional activities to their department head annually.
Research Affiliates are expected to comply with their primary employer's policies on outside professional activities. However, if an activity is Reasonably Related to the purpose of their appointment at MIT, for the period of their MIT appointment, they must report those Outside Professional Activities to their MIT faculty host on a rolling basis, as they occur, throughout the year, in compliance with the Institute's policies on Conflict of Commitment, Financial Conflict of Interest and Guidance on Outside Professional Activities.
Appointees to this rank are required to sign an Invention and Proprietary Information Agreement.

Staff Affiliate: Because of the unique relationship that the Institute has with both the Howard Hughes Medical Institute (HHMI) and the Broad Institute, there are individuals who are employed by HHMI or the Broad Institute and its partner institutions who work exclusively in MIT-assigned space. The appointment of staff affiliate is reserved for those individuals. Individuals appointed as staff affiliates are usually administrative or technical staff. Postdoctoral scholars supported by HHMI or the Broad Institute are appointed as fellows.
Staff Affiliates receive their salary from either HHMI, the Broad Institute or other non-MIT Broad Institute partner institutions. They are not employees of the Institute and are not eligible for MIT employee benefits.
Ownership of intellectual property is governed by collaboration agreements between the Institute and each organization.
Individuals holding such appointments are expected to report any Outside Professional Activities to their MIT supervisors on a rolling basis as they occur throughout the year in compliance with the Institute's Conflict of Commitment Policy, Guidance on Outside Professional Activities and Conflict of Interest Policy.

Visiting students are individuals who are enrolled in degree-granting programs at their home institution either in the US or abroad and are approved to conduct research on campus for a set duration. Visiting students are ineligible to enroll in or attend classes and, therefore, are distinct from cross-registered students.
Students who are pursuing an undergraduate or graduate degree at an institution of higher education other than MIT and have been invited by an MIT department, laboratory, or center (DLC) to do research in their fields of study may apply for Visiting Student status. Visits must be approved by the dean of the school or college where the DLC is located.
Visiting student appointments are limited to 12 months. Faculty hosts must pay a processing fee using discretionary (non-sponsored) funds. In addition, Visiting Student Fees must be paid in the Visiting Student Portal in full, prior to the student’s arrival. Additional policy information can be found in Policies and Procedures §5.5 and the Visiting Students Process page (requires Touchstone) and at the MIT International Students Office website, which includes a detailed DLCI Guide to the Visiting Students Program.
The International Students Office handles all visiting student applications (including those of US citizens). Details on the process and appropriate forms can be found at the International Students Office website.
Appointees to this rank are required to sign an Invention and Proprietary Information Agreement.
