If you have the itch to study abroad in college, get started as early as possible. Go to the study abroad office. Ask questions upfront, even if you are a freshman and do not plan on going abroad until junior year. The sooner you get started, the more you can prepare.
Language learning is one of the benefits of studying abroad because you immerse yourself in it. In school, out meeting new people at the grocery store, etc., the language is everywhere. Studying abroad forces you to use the language, which is beneficial to apply what you learn in class. But it is helpful to brush up on a few words and phrases before you depart. Pick up one of those mini guidebooks in the airport! They are overpriced yet full of practical phrases.
The top tips for studying abroad have to include getting your passport and visa. You literally cannot go abroad without them! But do not prolong this process. Depending on your host country and their passport and visa requirements, it can take a while. But do not make this first-time traveler mistake!
