An employment agent who prepared bogus documents to help four maids stay in Hong Kong was jailed for two years yesterday. Sandy Lee Siu-ming, 33, of the Sanbarry Employment Centre, admitted aiding and abetting the making of false representations to immigration officers. Between April 1994 and May last year, four Filipino domestic helpers approached Lee's agency for assistance, prosecutor Finny Chan told the District Court. Lee prepared fake job contracts and supporting documents for the maids to apply for an extension of stay and change of employer. She charged the maids $12,000 to $13,000. The maids presented the documents to the Immigration Department to claim they worked for genuine employers in order to obtain employment visas. Judge Richard Davies said the court should take a serious view of such offences and custody was inevitable. He adopted a starting point of 21/2 years and gave Lee a six-month discount for her previous good record.
