In order to stay in the United States as a full time student, you are required to have a student visa (F-1).  After you send us the complete application packet, we may issue the form of I-20.  Processing period for the I-20 form is approximately one week.  You will be asked to take it to a interview for an F-1 visa at the American Embassy in your country.  

To apply for an F-1 visa, visit travel.state.gov for detail information.
