The term 'TRAVELER'S NEED, MAYBE' can be solved by the four letter word 'VISA'. A VISA is a document issued by a government that allows a person to enter, stay in, or leave a country. It is typically required for international travel and is usually issued for a specific purpose such as tourism, business, or study. Depending on the country, a VISA may be required for a certain length of time or for a certain number of visits.
