I got a 457 visa and I wanted my girlfriend to come with me for good. We got married before I left my native country. We then processed her papers. After a few days of her arrival, I noticed changes in her. And after one month, she left me. I still pursued for her to take me back. But she doesn't want to. It seems she just used me so she can legally live in Australia. Can I file a case through immigration law so they will cancel her spouse visa?
