If the foreign student advisor believes you have the resources necessary for study in the US, he or she will send you a Form I-20 (Certificate of Eligibility for Nonimmigrant [F-1] Student Status). You will need to submit this form with your application for a student visa at the American embassy or consulate. You will also have to provide proof of proficiency in English (unless you are enrolling in a language program).

You will also need:

Form DS-156 (Non-Immigrant Visa form available from US consular offices),

A passport (valid up to at least 6 months after the completion of your course),

A 1-1/2 inch square (passport size) photograph (37 mm x 37 mm) showing full face against a light background,

Financial documentation (including both solid & liquid assets) & annual income of the sponsor if any

Visa processing fee.

The following documents of non-immigrant intent can bolster your case further :

Letter from the prospective employer.

Reference from somebody known to you who has returned to India after his masters.

Requirement for your masters in your native country.
