8老師，
我們收到綠卡麵試通知了，準備原件時，發現找不到兒子第一年錄取時那張I-20原件了，想問一下我們需要提供第一張I-20原件嗎？他前幾個月，因為正式確定了major, 剛拿到一張新的I-20，是不是和I-94一樣，隻要有最近的就可以了？
-Technically he needs to provide all the original I-20s since his last entry. But if he lost the old one, he may just provide the photocopy of it, and explain it to the IO. No big deal because the IO can find his record from SEVIS system, anyway.
