Thank you, dear 8老師. The problem is that his grand parents have been sick frequently. As a teenager, he is frequently rebelious, making me feel exhausted completely. For his grandparents and my relaxation purposes, he must go back this summer.
When might the danger come into being? At the embassy when he is applying for visa?
Will it work out if I let him stay in China for 6 months and decide what to do? 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.
