A few questions about tourist visas to China

Iranian tourists are advised to refer to local travel agencies to apply for Group Visa to travel to China.
The documents needed for tourist visa application include: 1) A passport valid for more than six months before expiration and at least one blank page in it. (2) One complete application form with one recent passport photograph (black and white or color) glued thereto. (3) other deemed necessary documents by the embassy. It normally takles 4 working days to process a visa. I'm not clear about the visa fee. Maybe you can contact th embassy directly for it: +9821-22296172 (Manned Service); +9821-22812500, 22816600 (Answering Service)
