INDEMNITY from prosecution will be considered for people who give strong evidence against groups organising illegal marriages of convenience.
The indemnity deals are part of a fresh offensive being launched by the Immigration Department to stamp out such scams, which can involve fees of up to $30,000 being paid to brokers.
Triads are known to have stepped up their involvement in marriages of convenience in recent years to meet the growing demand from women trying to overcome the strict entry requirements of the territory.
Assistant Principal Immigration Officer Chow Kwok-chuen said marriages of convenience were mostly resorted to by women who failed to have the necessary skills levels to qualify for residency in Hong Kong.
He said most of the women came from low income countries in the region and were forced to ''resort to other means of entry''.
Mr Chow refused to name which nationalities were most commonly involved in the scam. However, it is widely known that women seeking to marry Hong Kong citizens for the right to live here are generally from the Philippines and Thailand.
