I am an Australian wanting to visit the US for 6-12 months and it seems I have to apply for a B2 visitor visa. I have been online and not sure where I apply for that. I thought that I probably would have to go to Sydney for an interview but all I find online is different companies wanting me to go through them to process the application. I am sure if I do this I will be paying more.going through these companies. Does anyone know where I apply for a B2 visa, is it Sydney that I have to go to for appointment or is it the consulate of the state i live in and would it be the consulate or the embassy.
