Hi, I am a singapore citizen currently on a trip in kazakhstan and would like to check what do we need to do if I would like to enter china for more than 15 days. I was told that I would be able to apply for a china visa at the singapore embassy in beijing but there is no information available on the visa application process such as the time it takes to get it approve and the cost of application.

Could I get some advice on the necessary procedure?
thank you.
