I applied for an Intensive English Program for Spring 2006 (Jan - May 2006). I got accepted and got a 5 year student visa. I left to USA and decided to come back before I began my class because of some personal problems. I contacted the school to cancel the class. Actually I still wanna study that program though. Finally I came back to my country. I would like to apply for the Intensive English Program again but in Summer 2006 (May - August). Do I need a new student visa? Do I need to pay SEVIS fee again? Should I apply for the same school? Will I be in trouble by canceling the class and applying for it again? I planned to get Master's Degree in USA but the university I'm interested in needs me to fulfill College Calculus requirement before applying for it. I'm wondering if I could obtain a student visa by applying for a non degree student or something like that just to study Calculus and something else totally at least 12 credit hours per semester. Trigonometry & Algebra is a prerequisite of Calculus so I would need at least 2 semesters to finish them. I found out that there are many sessions opened in summer. Could I study those in summer? If yes, how many credit hours do I need to study? 12 credit hours for the whole summer? 12 credit hours for each session? Anybody has experience about this issues or know what I should do, please clarify me.....Thank you in advance
