谢谢8老师的详细解答。
还有一点关于递交I539 是我和先生各填一份吗?
-You may file one I-539 and your spouse files I-539A together. Thus, you only need to pay one I-539 filing fee: one check of $370 and two biometrics fees: another check of $170 (2 X 85). Talk to the school International Student Office and they can file these forms for the change of status for you.
交两个申请费?两张支票吗?一个信封寄出去吗?
不胜感激!
