My wife is a Thai citizen and I am a US citizen. Next month we are flying to Europe with a 24 hour layover in Shanghai China. My Chinese visa is still good but hers has expired. I am assuming that if we want to leave the airport to take a quick look at Shanghai, she will need to renew her Chinese visa, correct?
