I am an American researching moving to Portugal. I think the easiest way for my husband and I to move to PT would be to enter on a D7 visa and continue to work remotely for US companies. We can meet the savings/income requirement for this.
My question is, after entering on a D7 visa, could we later work for PT companies? Would we need to change our visas to work visas, or no? It seems as though, as long as we are paying PT taxes, it would be fine to stay living in PT on the D7 visa.
Our plan would be to eventually get dual citizenship in the US and PT (after 6 yrs living in PT). I think at that point we could live and work freely in any EU countries, correct?
