如何撤销澳洲500签证？
关于 签证/护照的取消和撤回 Cancellation 和 withdrawal ， 这两个概念有细微的区别， 但是很多申请人往往把这两个词搞混.
Cancellation 这个单词的意思是指， 你的申请被移民局完全取消了， 而你无法再获得这个签证.
Withdrawal on the other hand ， means your application has been withdrawn by you (the applicant) voluntarily， for example if you would like to apply for another visa after already being granted a visa or because of any change in circumstances that might affect your case. You can withdraw at anytime before decision is made.
It does not mean however， that this request will be approved automatically and that's where some people get it wrong： they think their applications have been cancelled. Withdrawal requests are always assessed according to immigration law， with all factors taken into consideration.
The difference between these two options actually lies in the processing steps. In order to cancel an application， Immigration Department must make every effort to contact applicants， but usually without success： phone calls， letters， emails etc… If no attempt was ever made to reach them – so called ‘unsuccessful attempts’ - then the department cannot proceed with cancellation unless there were exceptional reasons allowing such action， which may include fraud， misrepresentation etc. Otherwise， the only way to achieve cancellation is through judicial review. It could take years until getting back to court and having your file reviewed again; unfortunately many applicants wait too long when applying outside Australia ， thus missing out completely. They also need to pay full legal costs both during and after the trial， as well as possible interest charges. This procedure is extremely costly， especially since most appeals fail initially. A lot of times， even when cases do go against government， courts still refuse to order refunds of application fees， instead asking for further written submissions explaining why a particular fee should have been paid or should not have been kept. Even though you won， you did lose money． On the other hand， withdrawal is simple： just fill out online form； once submitted， withdrawal takes place almost immediately providing there aren't any outstanding issues needing further investigation. There are absolutely no additional charge associated with this process.
In most cases， withdrawal
