Hi Mr. Simon, thanks for your reply. Very helpful. Do I need to wait for my working permit/visa from my employer before going to the Chinese embassy to submit all documents needed for the processing. Do you have any suggestions on what to do first? Thank you.

yes, you need to wait for your work permit from your employer and the original visa notification form, when you get the 2 documents, please go to one hospital accepted by China embassy to do the Medical examination.
