You must bring a valid passport with an expiration date of at least 6 months AFTER the date of your return flight home. Every student not coming from the Americas or a European Union country should consult the following web site to ensure that they meet immigration requirements for your country of travel: https://travel.state.gov/content/passports/en/country.html
We recommend that you make two copies of your passport, one to keep with you during the course in case you lose your original, and one to leave at home, too. If you do not currently have a passport, you should start the application process NOW. It can take many weeks for your paperwork to be processed and a passport issued. For passport information go to: http://travel.state.gov/passport_services.html
You will not need money during the majority of your course. However, it is best practice during international travel to bring some money with you. We recommend a combination of cash and a debit or credit card (Visa charge cards are accepted in most populated areas). Semester students should bring $100. At the end of course, time permitting, students may be able to purchase souvenirs. They may also want to purchase food/snacks while traveling to/from the course.
Bring your flight itineraries, and a copy of the Costa Rica Arrival Info sheet sent to you by your Course Advisor (which includes emergency contact numbers).
