There is some discussion on the mailing list about visa to Hong Kong for Wikimania 2013.
List of visa-free / visa-required countries are available on [[wm2013:Visas]] [1] and its source [2].
Please check them out and determine whether you are visa-free to Hong Kong or not.
The processing time for a Hong Kong traveling visa are usually finalized within four weeks [3].
If you are confirmed to attend WIkimania and required a visa to Hong Kong, please send us an email with your name and nationality to
wikimania@wikimedia.hk .
This will help us to have a better sense for the visa problem.
