Minnesota handles visiting students through licensure exemptions rather than a sign-off for each school. Two provisions do the work. Minn. Stat. 148.271(6) excuses an RN licensed elsewhere from needing a Minnesota license while in the state as a student pursuing, say, a higher degree, for the practice that coursework involves. Minn. R. 6305.0300 subp. 1 then counts a program approved by its home state or province as board-approved for the student exemption, on one condition: whoever supervises the student there has a Minnesota RN license with registration kept current. Research turned up no extra approval filing for schools outside Minnesota.
Big sites can ask for more. Mayo Clinic, for example, requires an affiliation agreement with Mayo, an unencumbered Minnesota license with current registration, a background study through Minnesota's DHS, and faculty of record licensed in whichever state hosts the experience.
