My suggestion : you can apply F1/J 1 visa for yourself. F2 is hardly to say. It depends on how you luck.He, one of my friend, applied his F1/j1 visa in China four years ago, even his wife had F1 PHD in USA. He read his postdoc in USA and he got his PHD in Japan. Now, He gets his Green card and works in China as a 教授。Good Luck.
