What is a visa?
Visas are the permission that are granted by a sovereign nation to a traveler permitting entry into that country for a specific purpose. Most visas are stamped into the traveler's passport. The most common types of visas are granted for the specific purposes of tourism, conducting business or attending a conference or symposium, establishing temporary or permanent residence, or going to school. A traveler must follow very distinct guidelines and procedures established by each sovereign nation in applying for the appropriate visa category.
