It is important to issue the appropriate invitation to international visitors, even those who will not receive pay. Whether inviting faculty or others to visit for as little as a few days or hiring them for a longer period, please ensure that you are familiar with the immigration rules. There are a number of resources available at the University to assist you in navigating this process:
A quick, downloadable guide that flags issues that can arise with international visitors and provides information about where you can seek advice.
A comprehensive resource that includes the Immigration Toolkit and other essential information on immigration for faculty, staff, students, and visitors.
