I am moving home to CT after living in Australia and I want to bring an Australian teen back with my family. We are in the process of getting guardianship as he is an Australian citizen but what do I need to do on the USA side? Can he function as another member of my family or does he have to have a visa and follow strict guidelines? Public schools...be a charge because he is from out of country on visa? Anyone have any experience or knowledge you would like to share?
