A visa is essentially 'permission' to enter a country. If you are traveling to a foreign country, you need a passport, which identifies you to the foreign country, and a visa, which is permission from that country to enter.

Different countries have different requirements for visas. You must research what the country you are visiting requires. Some require formal requests via forms submitted before you enter the country, others will grant a visa just by showing up with a valid passport, some require no visas whatsoever.
