Washington, Oregon, Arizona are popular - and expensive.
University of Washington and Washington State are almost $50,000/year for out of state (and therefore international) so that’s out of your budget. University of Arizona is more than $43K/year – and you have to COUNT on tuition increases every year.
University of New Mexico is within your budget: about $35K/year
When looking at schools, always check (or first google “cost of attendance international students”) – no sense falling in love with a school you can’t afford.
