Please check with your local China embassies or consulates about the documents required for visa application. An official invitation letter can be provided on request after you are registered for the ICG2015. Please fill the Invitation Letter 2015 and send to email@example.com. Your letter of invitation is intended to facilitate the process of obtaining a visa but not a guarantee for the entry visa.
We recommend you submit your visa application a month before your planned trip to China.
