Please read this information carefully.
Some rules governing U.S. visas and immigration status are quite detailed.
The Form I-20 is a U.S. government form, but it can be issued only by specially appointed school officials. It states that the student whose name is on the form has been accepted for a full-course of study after applying to school and submitting all required academic documentation. Since you cannot get a visa without the I-20, your priority must be to provide us with the financial documentation we require before we will issue the form. We are very strict about proof of financial ability. Too little money causes pain and distress for students.
