I am an Indian national and I have a multiple entry B-2 visa of the US valid till 2016. I will be visiting US in Aug 2009 for a six months stay. During September 09 I will be joining my friends in US to go on a tour to China for tourism purposes arranged by China Travel Services, Houston. I will be applying for a double entry chinese tourist visa in India itself before procedding to US in Aug'09. We wiil be returning to US in third week of September after a 18 day trip via Hong Kong. We will be in HongKong for not more than 48 hr. Is a chinese visa good enough or should I get a Hong Kong Visa. I am told I can get a visa permit stamped in Hong Kong airport itself if the stay does not exceed 14 days. Pl clarify. Should I enclose a copy of my US Visa also along with my application for Chinese Tourist visa in addition to the itinerary/ airticket/passport copy etc as required by the Chinese Embassy in India?
