Do you need to apply for an Australian visa? Do you fully understand what it is that you have to do? Be careful, because small misinterpretations of the questions on the visa application form can result in a refusal to grant you a visa. At the very least, simple errors in translation can mean a delay in the release of a visa. As many visas need to be sent to an Australian consulate or representative by mail or by courier, a requirement to fill a visa application out again can take a lot of time.
