Yeah it's 580 now just for a single entry i think...scandalous!
Mine was 500 HK$ in yuen long for UK single entry visa bac\k in 3 days.
Hi, get the ferry or underground from TST to Wanchai and get it from the China Resource Building it only costs $670 for a double entry and lasts 3 months you can also get other types. It's situated on Harbour road and Flemming road just off Gloucester road passed the immigration tower. Travel agents will rip you off and they take two weeks here it takes three days to process take a recent photo and your passport with you.
i went to china resources building today and saw on the computer screen $150 single, $220 double, $400 multiple. 2 buildings make up china resources and the one to go to is the smaller one on the side. take the lift to 7th floor. i think they close during lunch time so you may want to avoid going in at that time.
