您的意思是,她还是需要在国内呆一年。但是这个是移民局硬性的规定吗?
-No, but B2 visa is for short visit and if you apply for it just after you visit US, the US Consulate will not approve it. Normally, one year or more is fine.
如果第一个签证期内她在美国呆了超过了半年,下次申请就一定要隔一年才可以,否则就一定会被拒签吗?
-Yes, most likely.
我是想让她能够长期和我在美国生活。
-No way, unless immigration (green card).
