I have a british passport, live in USA, visiting China this spring. How do i apply for visa?

Greene, first prepare the following documents: a valid passport, a photocopy of the data page of the passport, a completed application form affixed with color bare-headed person photo, the original and photocopy of your residence permit in the USA, and round-trip tickets and hotel reservations. Then go to the CVASC which is in charge of your residence region and submit the application.
