A Department of State Bureau of Educational Exchange Exchange Visitor Program page links to the latest guidance for Exchange Visitor Program sponsors and participants, and includes a Frequently Asked Questions section as well.
Note that among the ECA communications in this compilation, the Exchange Visitor Program's March 17, 2020 message states:
"In accordance with monitoring requirements, we ask that if your institution is moving towards an online environment, please report it to [email protected] using the Incident Report Form if you have not already done so. OPA is aware that as some sponsors move their operations to an online environment,their institutions are concurrently working on measures to decrease the density of their campuses (including moving exchange visitors out of university housing). If your institution is taking measures to relocate exchange visitors from campus housing, please detail this in your Incident Report and explain the options and/or resources you are providing to exchange visitors in terms of alternative housing. Please use this opportunity to remind your exchange visitors of the requirement for them to report to you within ten calendar days any changes in their telephone numbers, email addresses, actual and current U.S. addresses, and site of activity [22 CFR 62.10(d)(3)]. Please update SEVIS when necessary to reflect accurate program information including current U.S. address and site(s) of activity.
The Incident Report Form is available on the Academic Program Sponsors page on the j1visa.state.gov website.
