In Australia, the availability of a stay-back option, known as the Temporary Graduate visa (subclass 485), typically depends on the duration of your program. To be eligible for the post-study work visa, you generally need to have completed a program that is at least two years in duration. However, there is a Temporary Graduate (Short Stay Specialist) visa (subclass 485) available for international students who have completed a program shorter than two years, but it only provides a stay-back period of 16 to 24 months, depending on the circumstances. Eligibility criteria and visa regulations can change, so it's crucial to consult the Australian Department of Home Affairs for the latest information.
