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. Lengths of stay vary from an entire year to a few weeks during winter break or summer vacation. A short stay is certainly better than nothing, but a longer program gives you more time to soak up the host country's ambiance. Examine your personal goals as you look for a study-abroad program. Be realistic about your maturity level.
