You should provide the following documents:
1. Invitation letter (if you come to China for the first time). If you can not offer it, you need to offer an recommendation letter from your company or organization.
2. The financial statement and return air ticket might be required.
3. Passport and copy of its information page. Your passport should be valid for at least six months and have two blank pages.
