My fiance and I will be moving to Hangzhou in February so that he can attend the university there where he will complete his graduate degree. He has been accepted at the university. I am planning on teaching English while he attends classes. We were not planning on purchasing round-trip tickets because we may move to a country other than the US when his program is over in July. We also were not planning on securing housing until we got there and could take a look around. It doesn't look like any of the visa options fit with what we want to do. What should we do?
