I am building my own house and I want to buy from SEARS in Chula Vista, California, but I don’t want to pay double tax (in the US and Mexico) since I am going to import the merchandise to Mexico. Is there any way to avoid the payment of taxes in Chula Vista?

Hello,

I am a 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 Tunisia? 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
