An Ecuador visa will be issued on arrival for citizens of the United States, Canada, and much of Europe. This tourist visa is typically valid for 90 days. Check the stamp to make sure you know how many days they gave you.
You can extend your 90-day stay one time, for an additional 90 days. But, if you want to stay longer than 180 days as a tourist, you can get a special tourist visa at the consulate. Get this in advance of your trip, because it’s valid for up to one year.
Also, you can apply for such a visa once every five years.
