Dear Sir, good morning and greating from Kabul, - i need a bussiness visa

You should prepare the following documents apart from your passport, filled application form and a recent six months passport photo.
1. an invitation letter from duly authorized Chinese unit.
2. original and a copy of your business license.
3. a certificate of your current address. Original and translated verstions are required.
4. bank deposit (at least 4000 USD)
5. non-criminal record authenticated by your Ministry of Foreign Affairs
6. round-trip air tickets

If you have been China in recent five years, an invitation letter from duly authorized unit is enough.
