多谢8老师的及时回复!
最后想问下: 申请F2签证前是不是需要把H1B签证的申请撤销掉?
-It does not matter, but you need to get your passport back to apply for the F-2 visa if they hold your passport there.
这样F2的签证官会不会提出疑问,质疑我为什么改签F2呢?
-Normally they may not ask you this question. If asked, just say you need to return to US to stay with your spouse, and can not wait for the H-1 visa. It will not affect your F-2 visa, anyway.
非常感谢
