I think that this person will not send you his resume if he was reluctant to send you his passport. There is not much that you can do as if you try to report him what are you going to report him for and who will you report him to? Chances are if he is teaching in China his school is paying someone off so that he has a visa. So he would be protected if this was the case. Yes he might be working illegally without a proper visa but he will be finished his contract in a couple of months and be off elsewheres. There are so many teachers there working without proper qualifications that you would not be able to do much about it. I would let it go and do nothing with his application to your job.
