A group of legal immigrants, who had graduated from WA state high schools and were here on student visas, sued the University of WA in 2002 (I think that was the year) over a similar law. They won repayment of out of state tuition for the period that they were in school.
I have looked for mention of this court case on-line when other states took the same action and it seems to have been buried, but I know one of the students who participated in the case, a young man from Korea. He was forced to leave the country almost immediately after graduating and has been trying to get back ever since. He even tried enlisting in the US military and they wouldn’t take him.
When does the new governor take over?????
