Plan to get important documents, such as a valid passport, visa from your host country, International Student Identity Card (ISIC), and International Driving Permit.
Generally, you must have a passport to travel to a foreign country. The U.S. Department of State publishes comprehensive information online about passports. Carefully read this information.
It is very likely that your host country requires a visa for entry. A visa is an ink stamp or piece of paper put in your passport by a foreign government that gives you permission to visit for a specific time.
For definitive visa information, check with the embassy or consulate of your destination country.
International Student Identity Card (ISIC)
The ISIC photo ID entitles full-time students to valuable discounts. This cost of the card varies slightly by county but is usually the cost of a local cinema ticket and is available from your college or university. Learn more or purchase the ISIC here: http://www.isic.org/.
International Driving Permit (IDP)
Even if you won't be driving, it is probably a good idea to have an IDP available for emergencies. You can get an IDP from your local American Automobile Association (AAA), but first you must have a valid driver's license.
