Travelers can apply for a Hong Kong visa from the nearest Chinese
embassy or consulate. As an alternative, you may also submit your visa
application to the HKSAR Immigration Department either directly by post
or through a local sponsor.
To shorten the processing time, application forms and supporting documents can be sent by fax in the first instance. However, the original copy of the duly completed application form and the photographs required should be sent immediately to the HKSAR Immigration Department by air mail.
It is suggested that travelers contact and check with Chinese embassy or consulate in your country, or with Immigration Department of the Hong Kong SAR Government for the most updated information on entry formalities: https://www.immd.gov.hk/eng/services/visas/visit-transit/visit-visa-entry-permit.html
