I am 18 and will be travelling to china in september to study Kung Fu

You need an invitation letter from the Kung Fu school, which cannot be e-mail and should contain your information (i.e. full name, gender, date of birth, purpose of visit, date of arriving and leaving China, place of visit, financial support during stay there) and information of the inviter (i.e. name of organization, contact number, address, stamp of the organization, signature of the organization’s representative). If you have this letter, you can submit your application to CVASC in you place. Other basic documents are your passport, application form, photo.
