請問如何把O3簽證換成F1 學生簽證?
-File I-539. Talk to the International Student Office and they will help you out.
麻煩嗎?
-No.
大概需要多久?
-May take several months, case by case.
需要出美國嗎?
-Not have to. You can either change O3 to F-1 within US by filing I-539 or go to China to get the F-1 visa to come back. Up to you.
謝謝
