Hi Foxy,

One of my good friends has been teaching with L visas in Hubei. She has no university degree, so she can't obtain a Z visa. But after returning to Thunder Bay for a vacation, she was refused a new L visa for China. It would appear that the Chinese visa office wouldn't renew her visa because her string of Ls had cast doubt on the truth of her stated reasons for visiting China once again.

However, I guess you've got your foot in the door by being on Chinese territory as well as having a Chinese wife there to bat for you should the local PSB dare to refrain from renewing your L visas.
