To assist your visa application, the Organisers can issue you an official invitation letter. You can apply the invitation letter through this form at least two months before the Fair begins. After receiving and verifying the requested documents, we will send you the invitation letter by email.  It will normally take four to six weeks for the Immigration Department to process a visit/transit visa/entry permit application upon receipt of all the required documents. Please note the issuance of a visa is at the discretion of the Hong Kong Immigration Department.
