will the f1 status expire once if you graduate from school? , I have f1 visa for 5 years but I have graduated , and I want to go back to India , if I get admit in other school can I come back again with same old F1 visa?
Your sevis will get transfered to the new shool, if you get transfered. If transfer between the school for the same course, then I dont think you need to get it stamped unless the old F1 expires. But be ready to face questions at POE as to why did you change so many schools and what are you doing now. Consult and have your doubts cleared with your school DSO before leaving the country
If you are joining an entirely new course in a new school and if you are in India you need to go for a stamping.
