For a direct postal application, visa/entry permit label will be mailed to you directly by registered air mail if your application is successful. The visa label should be affixed onto a blank visa page of your travel document for presentation to the immigration officer upon arrival in the HKSAR. It will normally take four weeks to process a visit/transit visa application upon receipt of all the required documents. The Immigration Department would not be able to start processing the application unless all the required documents and information are received.
