20 states offer in-state tuition to unauthorized immigrant students, 16 by state legislative action and four by state university systems.
16 state legislatures enacted laws to allow in-state tuition benefits for certain unauthorized immigrant students.
These laws typically require attendance and graduation at state high schools, acceptance at a state college or university, and promising to apply for legal status as soon as eligible. At least 4 state university systems—the University of Hawaii Board of Regents, University of Michigan Board of Regents, Oklahoma State Regents for Higher Education and Rhode Island’s Board of Governors for Higher Education—established policies to offer in-state tuition rates to unauthorized immigrant students.
