Australia today unveiled a new points-based migration criteria that will lay higher focus on English proficiency and high-level qualifications rather than on vocational skills and experience, a move that could affect prospects of low-skilled Indian students seeking migration.Immigration Minister Chris Bowen said the new points test will emphasise the importance of English, work experience and high-level qualifications, and is designed to ensure no one factor guarantees migration.The new rules are aimed at toughening the rules of gaining permanent residency for overseas students with low quality qualifications. The new rules will encourage high skill workers and swap hair-dressing students with scientists.
