TWO Hong Kong-born children will be deported to China at the end of this month with their mainland mother. Wong Ka-wan, nine, and Sau-kin, seven, failed to win their right of abode in the territory despite having valid Hong Kong birth certificates and a local father. Their parents are not legally married so they fail to fulfil the criteria to be a Hong Kong resident. Mother Tse Lai-fong, 33, sneaked into the territory in 1984 as a mistress of Wong Shing-sam. Her illegal residency was discovered in May. The children's father is serving 12 months in Stanley Prison for providing assistance to his illegal immigrant mistress. The family of three are now homeless and staying at a relative's home in Wong Tai Sin. The children are studying at a school in Yau Yau Tsuen. Ka-wan said they did not want to go to China. 'There won't be any good cartoons to watch over there. I don't want to lose my classmates,' she said. Ms Tse said her only hope was the Government allowing the pair to stay. 'If they are deported to the mainland, they will not have an identity in China since they were not born there,' she said. The children's lawyer, Daniel Wong Kwok-tung, said the Government should allow them to stay on humanitarian grounds. Mr Wong has filed an appeal to the Immigration Tribunal. 'The children should not be penalised simply because of the marital status of their parents. In this case, the welfare of the children was not taken as a priority,' he said.
