I as an international student applied to different colleges for fall of 2018. Out of these universities, The University of Texas at Tyler had an attractive Scholarship of full tuition, housing & meal, and books. I emailed them if it was available for international students or not, and they confirmed it was available. I applied and got accepted in January. With my acceptance letter, they mentioned that my scholarship would only be confirmed if I paid the freshman confirmation fee of $100 before March 1. I paid the fee immediately on January. On February, they asked for $125 housing deposit and I paid that. Last month they issued my I-20 letter which mentions of my scholarship. I have a Visa interview appointment scheduled in a week. Yesterday, the university emailed me stating that they were out of budget and could no longer offer me the previously promised and confirmed Scholarship. I have rejected the scholarship from other universities as I was sure to go to this university after having received my i-20 and having scheduled my interview. I am totally frustrated now. They say they will give me a scholarship of $5,000 instead of $21,000. I am totally frustrated after having spent a year on the application process. What should be done in such case?
