Studying in America can be prohibitively expensive. Depending on your circumstances, you may be able to study there for free. Some of the potential ways to study for free include:
Have an outstanding academic record of achievement (including grades, skills, and English language abilities)
Find the least expensive universities or colleges and then apply for any eligible scholarships
Apply for scholarships from your country, the US, or your chosen university
Identify if your circumstances qualify you to study on some programmes in the US for free (e.g., if you are from an underrepresented minority group)
It is likely a difficult process to find a route that lets you study for free in America, but it is possible with persistence for some individuals.
