i want to make Chinese F visa in Indonesia

An invitation letter from the host company or the partner in China, or a letter from your company(Original letter, copy or fax are all acceptable) are required for business F application. Other documents needed are your passport, application form, photo. Sometimes, the round-trip ticket and hotel reservation are also required. If you were granted China F visa at least twice in past year, you are able to get a one year multiple. Otherwise, you can only get a single entry. You can use an agent if you do not want to handle this application in person. Fee is 300,000 Rupiah for a single entry and you should contact by yourself about the extra fee for service of agent. BTW, if your application is headed to CVASC, extra 240,000 Rupiah will be charged by the center.
