When I go back shanghai, should I use H1b?
--不一定,但最好keep H1
I heard that my H1 will expire immediately if I use AP, is that correct?
--不對
here I am asking two questions:
1. What kind of visa should I go back?
--用AP就不要簽證
2. What is possibblity to get a H4 visa in shanghai in our case?
--確實的結婚證明(公證),她可以申請H4
