If you are accepted to a Earth Expeditions course, you will be provided with a wealth of information you'll need to travel abroad with the program. Miami University requires that students traveling outside the U.S. purchase travel insurance, which costs about $28, and carry a valid passport. But again, if you're accepted to a course, you'll be provided with all the necessary information.
For information about passports, visas, travel advisories, and other detailed travel information, check out the U.S. State Department's Web site at www.state.gov/travel/.
To access information about traveler's health and vaccines, take a look at the Centers for Disease Control (CDC) Web site at www.cdc.gov and under the heading "Health and Safety Topics," click on "Travelers' Health" or "Vaccines & Immunizations."
