i am a singapore malay girl..and i like to marry my prc boyfriend..how can i apply visa in china?

If you are not married by so far, you should apply for a L type at the CVASC branch in Singapore. Prepare the documents, such as your valid passport and a photocopy of its data page, a completed application form affixed with your recent photo, and an invitation letter from your boyfriend. Then go to the center to submit the application.
