Dear All,

This is a great forum..and I hope that someone can please solve my dilemma.

I am an Tunisian national on J1 Visa in the US. However, I have never paid taxes in Tunisia. I did my PhD and was working in France for 5 years paying taxes there. I got my visa in france. Is my tax residency France or is it Tunisian? Because if I claim it to be Tunisia, there is no two years tax treaty. If it's France, what documents I need to claim the tax refund?
Thanks
