IMAGINE a Hong Kong Chinese on a tour in North America in the year 2000, with a Special Administrative Region (SAR) passport tucked in one pocket and a British National Overseas (BNO) passport in another.
Which passport should the person use when he or she tries to enter, say, Canada? Judging from the frantic efforts by the Hong Kong Government to encourage eligible Hong Kong people to obtain a BNO passport before 1997 and the fact that BNO passport holders are currently not required to obtain a visa to visit Canada, it is logical to expect the Hong Konger to use his or her BNO passport.
This is especially so because Chinese passport holders are required to obtain visas to visit Canada and the SAR passport is a kind of Chinese passport.
But there are reasons to suggest the BNO passport's supposed 'supremacy' over the SAR passport cannot be taken for granted.
Canadian immigration officials may likely frown on seeing the BNO passport, in which case the Hong Kong person will have to unveil his real identity as a Chinese national by flashing his SAR passport, according to the educated guess of a lawyer, William Clarke.
Mr Clarke used to teach at the University of Hong Kong and has written a number of articles on Hong Kong's immigration laws.
