A visa is a document that allows a foreign national to enter, stay and leave a country. It is usually stamped or glued into the passport of the traveler. In most cases, visas are required for travel to another country, but there are some exceptions. For example, citizens of the United States and Canada can typically travel to each other's countries without a visa. There are also some countries that offer visa-free travel to certain nationalities, such as the Schengen Area in Europe. However, even in these cases, it is important to check requirements in advance, as conditions can change with little notice. When planning a trip abroad, it is always best to consult an up-to-date travel guide or contact the embassy of the country you wish to visit.
