Regulations pertaining specifically to the Professor and Research Scholar categories are found at 22 CFR 62.20.
As participants in these program categories, foreign professors and research scholars engage in research, teaching, and lecturing with their American colleagues. Alien physicians in graduate medical education or training and short-term scholars are not included in this category.
The eligible participant shall not be a candidate for a tenure track position. Also, professor and research scholar participants may not be in the United States in J-visa status for any part of the 12-month period preceding the start date of their programs, indicated on their Form DS-2019. The 12-month bar is waived if the participant is 1) present in the United States no more than six months; or 2) participating in the Short-Term Scholar category.
At the discretion of the responsible officer, professors may freely engage in research and research scholars may freely engage in teaching and lecturing; this will not be considered a change of category. Incidental lectures or short-term consultations are permitted with the approval of the responsible officer so long as they are directly related to the objectives of the participant's program, and do not delay its completion date. Please consult the regulations for details.
The maximum Duration for both categories is three years. The responsible officer may extend a participant's program for up to six months to allow the research scholar or professor to complete a specific project or research activity. Extensions for a period longer than six months must be approved in writing by the Department of State. The responsible officer should submit a written request to the Department on behalf of the participant, no less than 60 days prior to the expiration of the participant's permitted three-year period. The fee for extension requests, payable to the Department of State at the time of application, is $198.
