還有兩個操作的疑問:
1) 如果我1月份file, 她在我485批準以後回來, 還能給她file I485麽?
-Yes, but she only can appplys for the B2 visa to enter US after your I-485 approval, no more H4.
2) 是不是在file的時候, 她回來, 簽字以後, 再回去?
-Not need to return to China. If she has to return to China, she has to wait for the AP approval and then, go to China.
