I have an I-20 for the Fall 2018 session and got my F1 visa approved. My college starts on the second week of August. Due to some family emergency, I need to postpone my travel for next semester, i.e. Spring 2019.
If I defer my admission until the Spring 2019 semester, and get a new I-20, will I be legally allowed to enter United states on the same F1 visa or do I need to reapply for a visa?
My F1 visa is a multiple-entry visa and is valid for the next 5 years.
