Like any life-enhancing experience, studying abroad requires careful planning. You need to make sure the courses you're taking overseas will meet the criteria at your home institution and will transfer back so you can receive proper credit. Get course descriptions from the overseas institution you want to attend and study them carefully. Your faculty advisor can help you find the right courses or curriculum. He or she might also have to preapprove your choice of institution and courses, so work closely with the advisor.
Finances are another factor to consider.
Costs for studying abroad largely depend on the country you choose, but you will probably be able to find state and federal financial aid or scholarships that will make the trip possible and affordable. Sometimes the countries themselves offer grants to American students who want to study in their universities. Language doesn't necessarily have to be a barrier. Some students welcome the chance to learn a new language or brush up on their skills. However, it's a good idea to learn the basics of the language of the host country so you can communicate on at least a rudimentary level.
