I am from India. I have B1/B2, H4, F1 visa with no denials.
I was to take admission in Spring-2018, for which I got my I-20 and F1 visa as well. Due to the health concerns of my parents, I had to extend it to Fall-2018. I applied again in the same school and branch, now they have accepted the admission and issued a new I-20.
