Hi. I am US Citizen, and my wife is Chinese. We want to visit Austria. What docs she need?

Hi, you need to prepare the passport and its copy, Chinese Hukou and ID, the application form, 2 passport-style photos, working certificate, round trip air tickets, proof of accommodation, bank statement, certificate of family relationship with your brother and other required documents. It may cost CNY 637 for the application. Just for reference.
