The Temporary Work Skilled visa 457 allows a skilled worker to work for a business that will sponsor you for up to 4 years. The business that sponsors you must pass certain criteria to be able to sponsor you. The business can hire you if the role that they wish to hire you for, is on the consolidated sponsorship occupation list. The Temporary Work Skilled visa 457 allows you to leave and re-enter Australia as many times as you like within the visa expiration date. If you are let go from your job you have 90 days to leave the country or try and get another business to take over your sponsorship. Usually the business nominates you and then you go and submit your application. Here is a guide of the documents I submitted to gain my 457 sponsorship. Certified copy of your passport Certified copy of your birth certificate A police check from your own country dating back 10 years. Certified copies of all your parchment qualifications Certified copies of your results from your colleges or universities Certified copies of any certification documents Certified copies of reference letters from referees Certified copy of your cv Two passport sized photographs with your name printed on the back A letter from your work place offering you a permanent job, with the date on it. Certified copies of work experience When I submitted my application it took less than a week to get a response via email. My visa was granted.
