Hey @pk, thank you for your answer.
2015 to 2016 and 2018 to 2019 were J1 Summer Work and Travel.
2019 to 2020 and 2022 to 2023 J1 Internship.
All of them were work related - I did not come here to study - even tho the J1 VISA is only issued for students, because you need to be enrolled in a college back in your country. I'm from Brazil my friend.
That's the main thing: it's unclear if I'm exempt or not. They consider all the J1 students? But then, if you read the tax website info, they say that you are only considered exempt if you are enrolled in college or school HERE (studying), which doesn't make sense because most of the J1 visas are for working not for studying.
