What kind of documents I need to submit to obtain a china visa? Thanks

In your situation, you can apply for Q1 type so that you can stay in PRC with him as long as you can. After you acquire your marriage certificate, please do not forget to get your marriage certificate certified by your Ministry of Foreign Affairs and then go to Chinese embassy to get it authenticated again. Authenticated materials will be required when you try to change your Q1 type into temporary resident permit at local entry and exit mangement bureau.

To apply for Q1, you need to provide your passport, application form, a recent passport photo, invitation letter from your huband, a copy of his Chinese ID card and your marriage certificate.
