I have my F1 Student Visa valid till 2020, issued in 2015. Last year, I deferred my admit to this year Fall 2016.
The University is same as last year, even the SEVIS number in the new i20 issued is same as last year.
Do I need to get a new VISA, any kind of stamping done on my old Visa or will my last year VISA suffice as it is?
