h1转H4是不是我自己在线交申请就行了,
-Correct. Just file I-539. provide a copy of your H1 approval notice with I-94 and your recent 3 paycheck stubs. Also provide the copies of your spouse H1 approval notice with his h1 I-94 and his cent 3 month paycheck stubs and your marriage certificate.
没必要通过老公(H1)所在的学校吧。要告诉或通过他们吗?
-Not need.
