Consult with your school advisor early on about studying and working in the foreign country of your choice. Understand that some countries may not participate in student work exchange programs. If that is the case, you will not be given a student work visa and will be unable to do any type of work in that country.
Visit the Council on International Educational Exchange Web site (ciee.org) for further information about obtaining a student work visa in participating countries.
Consider teaching English abroad if you are fluent in another language.
