Fill out a registration form with the marriage registration office. Your Chinese fiance will need to fill out paperwork at the registration office in their area.
Bring a birth certificate and a health certificate. You and your fiance will need to go to a hospital nearby and receive a certification of health and your fiance will need to get their birth certificate from the place they were born in.
Get a certificate of marriageability. This is to prove that you are not married to another person in your own country. The Chinese fiance will also need the same thing in order to show they aren't married to anyone else in their own country. You will need your certificate to be copied into translation of the Chinese language.
Bring your passport in order to show proof of who you are. You will also need a Chinese residence permit. Your Chinese fiance will need to have a letter from the parents giving permission to their child to marry a foreigner as well as a copy of the Household Registration Book or the Hokou. The Hokou contains Chinese laws pertaining to residency.
Pay the registration fee. With all of your paperwork together at the marriage office you will submit your application along with all of your certifications and all of the required information from the previous steps. Then the office will either approve or decline the application. A decision could take up to several hours. Upon approval you will then become registered for marriage. Three pictures will be taken of the two of you and then you will proceed with your marriage and then be given a marriage certificate.
