What is the purpose of your visit?
You can not get a multiple Chinese visa if this will be the first-time application.
You can submit the application in Vienna. In addition to a valid passport (with a minimum validity life of 6 months), an application form with a passport-size photo attached, return flight tickets and hotel reserve confirmation, you also need to present a Austrian visa or residency permit.

Hello,

Thank you for the reply. My boyfriend lives in China so I am going to visit him for 2 weeks. Do I have to have hotel reservation anyway?
This will be my first time in China, yes.
I have no visa in Austria as I am EU citizen already so I don't need any kind of permit here. Nevertheless, of course I can show where I live in Vienna.
Thanks a lot!
