Student Visa (F1, F2, M1, M2)

I applied for J1 visa at Chennai Consulate. I hope explaining in steps would be helpful for future applicants.
1. Pay visa fees ( $100) at HDFC bank and get the receipt. Yellow receipt should be shown at the consulate.
2. Pay sevis fee if required, ( visit http://www.ice.gov/sevis/i901/)
3. Fix visa appointment online (https://www.vfs-usa.co.in/Home.aspx)
   Documents required to fix appointment
1. SEVIS generated Form DS-2019(Relevant documents based on visa class)
2. Passport
3. Receipt issued by HDFC Bank
4. E-mail address

4. Interview.
     My appointment time was at 8.15 A.M, I went there at 7.30 A.M, but it is better go at least one hour earlier. There are few processes to be done before appearing for the interview like screening of documents and finger prints.
    Few sample questions are already in this site, I prepared well for the interview and had all the documents ready, but the consular asked me very few questions and he did not even ask for any documents, the consular took just 2 mins . For few persons they took more than 7 mins. You need not worry if you have all the necessary documents and all are true.
