There was just an article about this about Indiana specifically. The public schools charge higher tuition for international applicants and this will likely negatively impact domestic students as tuition will end up going up.
“The report highlights a notable drop in international student numbers, with Purdue University’s international graduate-student enrollment falling from 6,100 in 2024 to 5,283 in 2025. Indiana University also experienced a 14% decrease, with 5,645 international students enrolled in 2025 compared to 6,578 in 2024.”
