回複：我有新的I-20,但不知需要遞交什麽材料延期?能否詳細一點

F1 status holder's change or renewal I-20 does not need to file with USCIS. Your school DSO should take care of it, should they decide that you need to do F1 reinstatement, because you have violations or with > 5 months gap, they will endorse you to file I-539 with USCIS.
