Citizens of the United States, Canada, most European countries, Australia, Canada, Japan and New Zealand normally receive 90-day tourist cards when entering the country. A yellow slip of paper will be stapled or folded into your passport – don’t lose it, as you’ll have to turn it in when you leave, or get it stamped if you extend your stay.
You can extend your stay once for another 90 days. After that, you’ll be required to leave the country for at least three days. To extend your stay, take your passport to any immigration office and ask for a prórroga (visa extension); you’ll have to fill out a form and pay US$20. Practically every city and town in Honduras has an immigration office (migración) where you can do this.
