Each High School, College or University has different admission policies. You can find eligible schools on the Department of Homeland Security’s web site: https://studyinthestates.dhs.gov/school-search
Each institution will tell you what is needed as part of the admissions process. Additionally, you will need to provide evidence that you have funds to support yourself during your educational program as well as medical insurance coverage for the duration of your time in the United States.
Once your application is complete, the institution will review all the supporting documents and a decision regarding your admission will be given.
To accept an offer of admission, you must submit the necessary payment for tuition and related costs before your Form I-20 will be issued. You can then continue the process of applying for your F-1 Student Visa.
