If you marry in China, you hav

immigrant visa for your wife in U.S., and your wife has to wait at least 1 year to get visa, from my experience, I waited for 1 year and 3 months. Once your wife arrive in U.S. any airport, the immigrant officer will give her a temporary green card that is a seal on her passport. After 2 weeks, she will receive the green card that will expire in 2 years.

And I don't know anything about your working issue. Hope it will help you.
