We see that language education in America is gaining popularity. In this case, the question of how I can get a visa may come to mind. Firstly, if you say "I have a Schengen Visa" or “I have a green passport to apply to a school in America”, we must inform you that you are wrong. Because these documents are not enough to be voiced in America. Related, Schengen Visa is not a valid type for America. For your travel/study in America, you must apply to the American Consular for the relevant visa. Likewise, having a green passport is not sufficient for visa-free entry. Again, it is obligatory to apply for a visa to the American Consular.
The type of visa that people who want to study language in America should apply is the F1 Visa. To be able to apply for this visa, you must present a document proving that you will be a student in a language school in the USA. The most important document that must be included in your application file to apply for an F1 visa is the I-20 document. This document is sent by the school where you registered for language education in the USA. You cannot apply for a student visa without this document.
