An immigration consultant who submitted bogus documents to the New Zealand Government was jailed for 21 months by District Court Deputy Judge Ian Candy yesterday. Shirley Young Hsiao-ling also overcharged a client $80,000 for a migration application. Young, 25, was found guilty on three charges of theft and one of using false instruments. She had pleaded not guilty. Prosecutor Mahinder Panesar said Susana Chan Yee-may had instructed 1NZ Company to help her emigrate. Ms Chan testified that Young told her the fees would be $180,000. She had paid a $50,000 deposit and was asked to sign several documents. Ms Chan said she did not know what the papers were. The balance was paid later. However, it was the company's policy that the maximum charge should not exceed $100,000. Young transferred $110,000 either into her bank account or that of her mother and had returned $30,000 to 1NZ.
