Actually, a Hong Kong visa can be applied from Hong Kong Immigration Department by POST directly, even there's no Chinese embassy in your city, or there's something trouble with Chinese embassy.
Please refer http://www.immd.gov.hk/ehtml/id1004.htm
You may print out the PDF application form, fill it and attach necessary document such as passport COPIES, mail to Hong Kong directly.
Note:
1. Email address is very important because HK immigration will contact you by this way.
2. As now, I only know payment should be made by HK Cheque in HKD, or let someone else in HK go to the counter to pay for you. (It is better to ask someone in HK to help you)
3. The process time is much longer than an embassy, it usually takes 4-6 weeks.
4. Fee HK$160(approximately US$20).
5. The visa is a small seal paper, give you directly, and you have to paste to your travel document by yourself.
In addition, since the visa process of Chinese embassy is sometimes "terrible", I would like to recommend Wikimania Hong Kong to help with visa application, not the "invitation letter", but to collect the documents, submit to the local Hong Kong Immigration counter in Wan Chai collectively, receive the visa and send to applicants before the conference. That may be the most convenience.
