Funny anecdote is that when I used to be intern from Poland on J1 (~5500 USD per month), savings from 3 months of internship in USA divided by 9 months were higher than average salary in Poland. We got most of taxes back. We also had free tuition and great scholarships from EU. It was quite easy to get the internship. Back in my time, ~2011, ~1/3 of students from my alma mater, Warsaw University, did J1 internship in USA.
