Hello, Maiamu - thank you for writing!
For our GMAT courses, we're unauthorized to grant student visas / I-20s, but we don't require them, either. If you're in a Veritas Prep location on a travel visa or any other sort of documentation, you're eligible to take our course, or you can also take one of our Live Online classes (
http://www.veritasprep.com/online-offerings/) wherever you are in the world.
We hope to have the opportunity to work with you toward success on the GMAT and in business school!
Cheers,
Brian
