Where do I submit my visa application? How much does the fee cost?

Hi, you should submit your application to Chinese embassy or consulate in USA according to your location. For application that should be issued by the Embassy/consulate, the processing takes 4 working days. Fee is $30 per person.
But if your application is required to be referred to the Immigration Department of the Government of the Hong Kong Special Administrative Region (HKSAR) for processing, it normally takes about a month. An additional $20 of telecom liaison fee should be paid upon submission of the application.
