I just got back from Ecuador and I figured out I still have some large amount of Ecuadorian dollars with me and I though I could exchange them for US dollars but it turned out no exchange office around offers this service. So I thought on going in US bank but am not sure if US bank would accept Ecuadorian dollars? What do you think?
I am sure US bank would accept Ecuadorian dollars, why not. But eventually if it turns out to be failed you could always try going to a world bank. Anyway though you haven't mentioned where you live in US but of it is some big city you may find some exchange office in some Ecuadorian district or whatever and that is where you could also exchange your Ecuadorian dollars but generally I think that US bank would accept Ecuadorian dollars.
