During a recent discussion over drinks, Hong Kong-born ethnic Indian barrister Vandana Rajwani and friends touched on the issue of racism, a topic close to her heart.
Then someone remarked, tongue in cheek: ''If you are in a hurry at the immigration counter in Hong Kong airport, never stand behind someone with dark skin it will take you ages to get through.''
For Ms Rajwani, chairwoman of Hong Kong Against Racial Discrimination, the remark not only elicited a laugh but bitterness.
The treatment of visitors and Hong Kong residents from South Asia India, Pakistan, Bangladesh and Sri Lanka by immigration officials has become a hot topic of discussion recently following allegations of discrimination from Indian writer Amit Chaudhuri and classical singer Shubha Mudgal.
''I'm fairly certain that racial profiling is one of the considerations that's taken when they select individuals for immigration checks. South Asian are more likely to be picked on than Caucasian people,'' said Ms Rajwani.
She has held discussions with community groups and attended forums which have led her to a conclusion: the problem has been exacerbated by the September 11 terrorist attacks in the United States, with many South Asian visitors to the SAR facing longer and more stringent immigration checks.
