回複：Thank you, dear 8老師, but

When might the danger come into being? At the embassy when he is applying for visa?

-Don't see any problem as long as you keep your status e.g. F1, J1 or H1.

 

Will it work out if I let him stay in China for 6 months and decide what to do?

-Fine. No time limit.

 Our field is very bad with job market and I am not sure about offer. If I can get one, he can return. If I cannot, I would go back. No need to hang around under such circumstances.
