Z (Work) Visa is only issued to foreign experts who intend to work in the P.R. China for a period of time such as one year.
Foreigners who do not intend to work for a relatively long period in the P.R. China - or who wish to take a short-term travel – are not required to apply for this permit. They can apply for a Business Visa (F Visa) or Tourist Visa (L Visa).
