Hi Deanna, Say you come for a week — that’s seven days and then two months later you come for 10 days, that’s 17 days… and so on… so you’ll be fine as long as you aren’t in the country more than your allotted amount in one year, from your first entry through your last entry.
No, we are not dual citizens, we are “residents” of Ecuador. The rule is that you must not be out of the country more than 90 days total during each of your first years on your resident visa. We met that requirement several years ago so we can travel freely.
I’ll ask Edd to help with the rest of your question.
