Due to change of SEVIS ID, Got another call from visa consulate to reappear for a interview.

I was appeared for my F1 visa interview by January 16th but due to some sort of administrative processing I could not joined my university which I was intended to, so I defer my admission from spring to fall, 2018. Now since my SEVIS Id is changed and issued a new I-20, I got a call from visa consulate to reappear for an interview with my new I-20 and all relevant documents. Please let me know whether anyone have been through similar situation and share their experience.

hello iam in the same situation. but i want to know do we qualify for visa interview waiver program or we should go for interview like before.
