I got a chinese visa through my boss but we didnt go on the trip, now im no longer with the company.

Tito, If your old one expires, you need to apply for a new one. what is your purpose of coming to visit China? You know, the requirements vary according to the type you apply.

Thanks Ted, I'm coming to just sight see China. The ist visa was for business F, because I was meant to come with my boss. But I'm no longer working with the company. So I'm coming foresight seeing
Please what are the requirements.

Tito, you should apply for a L type for your visit to China. However, it seems that Chinese embassy in your country doesn't issue L types. They just issue F, M, X1, X2 and Z types. So I think you need to get another F type. Since you already applied for the F type, you should know what documents are required.
