Hello, hope you are fine. I'm an au pair in Philly, but tired of this work and this company, I really want to study here, and spend more time here in the US, I have a j-1 Visa with a valid DS-2019, so my question is: how can I change my visa to F-1? And if my DS-2019 is cancelled, would I be illegal? And everything in the future would be more difficult if I want to change my Visa status? Thank you for your answer!
