Hey can you tell me about the affidavit you are talking about? Even I am an international student that is on visa in USA and got accepted in both as a CS major
Do not know the post you are responding to since you made this a new thread, but for the answer see https://admissions.illinois.edu/Content/docs/Residency_Affidavit.pdf. You need to be able to answer all four questions “yes” to qualify for in-state tuition. The third question is a little ambiguous but it is asking whether you attended school in Illinois for at least three years before the date of high school graduation.
