Hong Kong Business Visa

Dear Sir

I'm a Sir Lankan passport holder working in Bangladesh for a Hong Kong/Chinese multinational company. I need to get urgent business entry permit to attend meeting in my head office located in Hong Kong. I have inivtation letter from my Hong Kong head office. If I come to Sri Lanka and apply it for Hong Kong via China Embassy in Colombo, can i get it within 2 days?

Please note I have traveled several times to Hong Kong and China before. So I have previous visa chopped in my passport. Thanks to advise.

Best Regards
Indika
