Question: What is a Visa?
Answer: A visa is an endorsement stamped on your passport by foreign customs officials that allows you to visit that country. You get a visa from the country's embassy or consulate (check consular sheets for embassy locations and, in some cases, websites). "Visit", as used above, means the reason for entry. In your case, it may be tourism or work (volunteering and studying abroad are usually considered tourism). Many, many types of visas exist based on country and type and length of visit. Check here to ascertain whether you need a visa for the country to which you are traveling, and find out about work permits here. While you're at that, look for jobs before you go, too!
