Named colleges in that article include:
Howard University
Louisiana Tech University
University of Texas - Arlington
University of North Texas
St. Cloud State University
Note that the first two are in the list at http://automaticfulltuition.yolasite.com/ – you may want to verify with the schools that international students are (still) eligible for those scholarships, and how your grades or GPA would convert to the usual 4.0 scale used in the US.
