<prompt> Human: Ill spare giving what I believe to be excessive details, but if Ive left anything out please ask! Im a full-time undergrad student and will be going to live with family in Australia for half of my summer while Im also taking a couple of online courses from a home CCollege. The purpose of my trip isnt really to vacation but to gain field experience. Im a pre-med student and I have family there who are physiciansacademic physicians Ill be shadowing, helping on research projects, and conducting other misc. works.While Ill have no expenses while living there thanks to them, Im financially not in a good spot and am hoping to make some money while living doing whatever to pay my parents back to funding my plane ticket. My real questions are: Would I need to obtain a work visa? What would taxes on the money look like after returning? Would I have to pay AUS and USA taxes on that income? Thanks for the help!  <response>: yes, you would need a work visa. you would have to pay AU taxes on what you earned there. you would not have to pay US taxes.
