Hi!
I'm a dutch national staying in the USA as a J1 scholar. My trip is less than two years and I've been exempt from paying tax as by the Netherlands-US tax treaty. Per treaty definition I have to keep my stay under to years, or will have to pay the two year taxes retro-actively.

My question is, when can I come back on a different visa without forfeiting my exemption? I'm currently considering returning on a short stay J1 visa next. I understand I couldn't claim the tax treaty again, but would it also forfeit my previous exemption.

Kind regards, Philip
