I am British from UK but living in Nigeria. how do i apply for the visa to the fair in April 2015?

Frances, you may contact the service center of Canton Fair to send you an invitation letter. Then you can bring your passport, filled appilcation form, a recent passport photo, invitation letter and your resident permit in Nigeria to apply for a M type from Chinese embassy. After you get the M type, you can go to Guangzhou.

Tel of the service center: 86-20-28-888-999
