【求助】What is SEVIS form?

有人知道什麼是SEVIS Form嗎?
麻煩大概形容一下

謝謝

Are you a student?
It's a replacement for I-20 (orJ-1.........)
It's for foreigners, such as international scholar, student.......
so the INS can have a clue about the foreigner's whereabout

問這個問題會不會太@#$%^^

你是剛來的喔:adore:

Replacement for I-20?
是不是就是那份 要離境時要拿去給advisor簽名的那份東西啊?
