I've been at the same company in Sydney for 3 years, having been in Australia for 4. They've been sponsoring me on a 457. Now I want to apply for my PR so I can look for work at another company (in Sydney). Is this possible? I have been told that if I apply for my PR now I have to sign something to say I'll be staying at the same company for a couple more years. My intention is to leave the company as soon as I have a PR, but am not sure if this is possible. Please help!
