The US has over 4000 universities.
They are all in different locations; they are all different in costs, weather, topography, population, and personality.
Some are in the city; some are in very rural farm communities. Some are in large cities. Some are in locations that don’t have nearby airports. Some colleges have 40 students and some have 50,000 students on campus.

Your issues that you’re going to need money because some of these colleges will cost anywhere from $40k-$90,000 US per year. So you start with your budget and you “Google” universities with international scholarships.
Then you go to each individual university ‘s website and learn about the school where you plan to apply. Learn about the environment. Learn about the costs. Learn about what they expect from their new applicants in regards to coursework, grades and test scores. Make sure you go to the financial aid page and find out if they will provide funding.
