I am a Bangladesh by Citizen living in Hanoi, Vietnam for over a year. I would like to go for a personal visit to HK for coupler of days. I have heard that China embassy deals with HK visa here in Vietnam. I also have come to know that for issuing HK visa an invitation letter is required from HK. I work for a HK based financial organization. My company will provide all type of papers related to my employment with the visa application, but will not issue any invitation letter as it’s not an official visit. As I do not have any channel in HK to get such letter, may I know if there is any other alternative way to get a HK visit visa without submission the invitation letter?
