Yes, I vaguely remember that during our first term living in El Salvador, we were on a six-month tourist visa, so that every six months we had to drive the four hours or so to Guatemala for a short vacation and then reenter the country and get another six-month tourist visa, and so on for the three years of our first term. During our second term we were on a residence permit, I forget why that was so, and we no longer had to make the obligatory trek to Guatemala every six months, so that was nice.
