Hi,

I am a US citizen and three years ago I married a chinese national since that time my wife has received a US green card (valid for 10 years) which allows her to live in the US. We both work in the UAE and therefore have a valid UAE work visa. My wife travells back to China to visit her family which is not a problem considering she holds a valid UAE visa. However when I retire we intend to live in the US but make trips back to china at least once a year. With her US green card can my wife, once in China on a visit, return back to the US without trouble from the Chinese authorities at the airport? She does not hold a US passport and therefore does not have dual nationality.
