I really wish I could remember, there was a place that sorted a business visa out for me years ago and all I needed was a business card, I didn't even have a business. I designed a marvelous card though, calling my fake company 'PEACE EXPORTS', then on the blank side of it, as a personal joke to myself had the words in large letters 'RING PEACE'. I know it's no help to you, sorry, just tickles me remembering it.

they allow u to go to hong kong but only from a few countries other countries you have to go back to your home country to get a visa si i would check i think us and candadians can go to hk
