Dear sir i am small scale industry person. I am wondering to visit china for business purpose .

Hi, if you know anyone in China, you need to apply for business M with an invitation letter from China. But if you don't, then you can only apply for a tourist L instead. Original copy of recent 6-month bank statement, Personal written statement and a Round-trip air (train,ship) ticket and the hotel reservation sheet are required. When you get all these documents ready, you can submit your application to Chinese embassy.
