The term GLOBE-TROTTER'S NEED can be solved with the 4 letter word VISA. A VISA is a document issued by a government that allows a person to enter, stay in, or leave a country for a certain period of time. Visas are typically required for international travel and are usually obtained from the embassy or consulate of the country being visited. Visas are also necessary for those wishing to work or study abroad. Therefore, a VISA is an essential requirement for any globe-trotter.
