Sir my visa interview was scheduled on 14th august 2012, I came to the consular. I had not submitted SEVIS fee and they told me to submit the sevis after which only they will allow me for the visa interview. I tried but was unable to get the sevis fee submitted that day and now they told me that i may take another date for the VI. deadline of my university is 23rd aug so I think I cant take any date further for this session. because I have not attended visa interview so am I eligible for booking date in future and if yes can i book the date for another session within a year?
