Chinese Visa

To work in China you must have a Z visa. This visa is good for only one entry. A multiple entry visa is much more expensive and difficult to get. There is a date "valid until" date. You must enter before that date or get another visa. To get a Z visa you must have a document inviting you to work for a work unit. A visa cost you $30 US if you are willing to wait a week or $60 if you need it in a day. You need a form filled out and two passport photos to get one. Expect long lines at the Chinese consulate or embassy. There is a consulate in San Francisco and the Embassy is in New York. The visa consists of an entry in your USA passport.
