I would like to second UT Dallas and also encourage you to consider TX A&M and Baylor if you are named a NMSF.
UT Dallas is very strong in STEM fields, A&M is a top university with many opportunities, and Baylor is a school that students love with lots of school spirit and a nice campus
Travel costs by plane plus room & board should keep your costs less than $20,000. NMF scholarships provide for free tution at these schools.
